01 Civic hesitates / stumbles on acceleration...help Been trying to figure this car out for a while now. In jan of 2010 it had the transmission overhauled. Haven't had any issues with it until now. It stumbles and hesitates sometimes right after it is turned on from sitting overnight. Does it once and goes away. Then while siting lets say at a red light, when I go to give it gas it stumbes for a second then clears up. No CEL's and no codes stored. No overheating as headgasket was done about 10K miles ago. Anyone point me in the right direction? |
Re: 01 Civic hesitates / stumbles on acceleration...help Hesitation/stumbling could be a lot of things. Do a full tune-up, might take you two hours or so, but will likely fix your problem. |

Air filter was changed about a month ago. I think thats about it as far as tune up on this caar unless you guys can tell me what else to check... |
Re: 01 Civic hesitates / stumbles on acceleration...help i was gonna say plugs but you beat me to it |
Re: 01 Civic hesitates / stumbles on acceleration...help Tune-up things to do after your plugs and air filter... To Clean: - Clean Throttle Body bore+butterfly with Throttle Body Cleaner and a Toothbrush (if you remove the TB to clean, you can reuse the gasket as long as it isn't cracked/damaged). - Remove IAC from Throttle Body and Clean with Throttle Body Cleaner. - Remove PCV and Clean with Throttle Body Cleaner (spray inside and shake to dislodge junk and ensure it is operating properly). Inspect the PCV hose for damage and replace if necessary. (PCV washer can be reused) - Disconnect EGR valve and spray inside of it with Throttle Body Cleaner (You will need to scrape off and replace this gasket). To Replace: - Replace the Fuel Filter (in-tank). Other that can help: - After the remainder of your tune-up and the fuel filter is replaced, dump a bottle of high-PEA fuel system cleaner in your gas tank at your next fill-up and run to "E" to let it maximize its cleaning time. (a bottle of Red Line SI-1 or the larger 20oz. bottle of Techron Concentrate). This will clean injectors and intake valves. Other things that won't help your hesitation, but is a good idea while you're at it: - Clean your battery terminals with a wire brush, and coat with a light layer of dielectric grease to prevent any corrosion. - Check and top up your fluids, inspect belts, and check your tire pressure. (Don't count on your quick-lube place to do it, I've had them miss a tire with low pressure even though they were all "checked".) |

That strainer in the tank isn't sold separately from what I have seen online. I've taken the pump assembly out before to look at it. I'll have to clean the TB and IACV when I have time. maybe there are some instructions here. This car doesnt have a EGR valve from what I know about it. |
Re: 01 Civic hesitates / stumbles on acceleration...help I have an 01 Civic EX, so I don't think you car can be too different... I replaced my filter just fine with this part: http://www.rockauto.com/catalog/rafr...&parttype=6208 ^ BECK/ARNLEY Part # 0433012, $29.79 @ RockAuto And there should be an EGR valve... |
Re: 01 Civic hesitates / stumbles on acceleration...help You could have a dead spot in your throttle position sensor. It would cause your issue and not throw a cell. You need a volt meter to check it though. If you have a volt meter than just hook up the positive lead to the signal wire and the neg. Lead to ground. If it's bad you'll see a dip or spike in the meter whiel opening the throttle. The most likely cause of your issue is the ignition system, pull out the coil packs and look for white lines on the boots that connect to the plugs. You could be getting a lose of the secondary ignition through the boot. The EGR could also be sticking, but that would cause you issues all the time. |

Thanks i didnt know that piece was the fuel filter. I thought the pump just had a strainer and thats it. Ive taken the pump off before. Didnt know that piece was the filter. As far as EGR i dont think the SOHC has one. |

Just need to find which wires what. |
Re: 01 Civic hesitates / stumbles on acceleration...help Anyone know where I can get a TPS from that isnt off a used TB? |
Re: 01 Civic hesitates / stumbles on acceleration...help I went ahead and ordered the pump filter and the strainer. Hopefully that solves my issue since a friend of mine had the same thing happen and turne dout it was the filter. I'll keep you posted. |
Re: 01 Civic hesitates / stumbles on acceleration...help Changed the pump filter and the strainer. Details in this thread I made into a How To: https://www.civicforums.com/forums/1...ml#post4559759 |
Re: 01 Civic hesitates / stumbles on acceleration...help so was the strainer clogged at all, or just the filter. and any pics of the actual filter? i was thinking they only had strainers for this car. |

Re: 01 Civic hesitates / stumbles on acceleration...help So did it fix your issue at all? I have a 05 civ and im not sure if it exactly the same as what your car is doing but I get hesitation in acceleration starting from 1st at times. The car starts off then it slumps down and then picks back up and goes. It might be due for a new clutch soon but I am not sure if thats whats really causing the issue. I recently had the timing belt changed and I got odd backfires when driving a little hard when rev matching and downshifting. So im am not sure if the timing is off and may be causing the dirty start in acceleration and backfires or the backfires are simply caused by the CAI and stock exhaust taking in too much air and that the stumble in the accerlation is a whole different issue. Anyways let me know if this fixed your issue and if the way I describe my issue sounds like the same as yours. I rather change smaller parts before jumping to larger issues/costs and find out that it wasn't the problem. |

This seems to have cleare dup my problems as before I could reproduce the problem all the time. I cant now that the filters have been changed. |

Re: 01 Civic hesitates / stumbles on acceleration...help I did't know that there was a filter at the top of the fuel pump. Good post. |

Dude, are you saying you stomp on the pedal and the car rears up then kinda passes out then comes back up with a fury? Cause if so my 05' does that to. I'll come around a corner, lets say the roundabout to an on ramp, at about 35 or 40 and then punch the shit out of my accelerator and that car will gush some speed. But when I start from a dead stop the engine slumps then winds rite out like a ****ing cheetah on steroids. I get little horsepower out of her so the acceleration isnt that great. However, I would like to get all the power from the moment I stomp on the pedal or press the pedal. So if what your saying above is what im saying then that also is my problem. :russian: |

I read the thread on how to repair this issue(great job by the way) and recognized the comment of (having to turn the car over longer than usual), is that a common dead give away for having to do this repair? I dont have that problem unless im running the old girl real low on fuel. I have, however, slightly tugged on the accelerator cable and felt some slack in it. Could that cause the same or simular result talked about in this thread. Could slack be normal or should that cable be tight as a nun. I have not been able to locate any other identifiers thus far and my services could be better but they are not lacking or poorly attended. :russian: |
Re: 01 Civic hesitates / stumbles on acceleration...help Cool. My slack is not great but it exist. I would say about a 16th of an inch slack before the throttle lever begins to move. I have cruse control in my EX. The cable in the back of the picture has the slack the cable in the fron has none. Do you think the cable in the back is the reular cable and not the cruse control cable? How does one tighten either or? Here is a pick of the cable I am refering to. |
Re: 01 Civic hesitates / stumbles on acceleration...help shit cant figure out how to put pictures on here. But it is the cable in the back nearest the firewall.:russian: |
Re: 01 Civic hesitates / stumbles on acceleration...help Im not sure how to remove the slack on the throttle cable so I can't help you there. I can however report that the car was taken on a 4 hour road trip this past weekend. No stumbling or anything after reaching our destination and having to go through the towns red lights or anything. Problem solved. |
Re: 01 Civic hesitates / stumbles on acceleration...help Cool. Thats good news. I'll have the slack looked at straight away.:russian: |
