What's up guys, I just had my timing belt, alternator belt, and power steering belt replaced yesterday. Seems like steering is improved (bit tighter) but the weird thing is the gas pedel seems tighter and the
idle is a bit lower. When I very first drove it away and stopped at a red light, I pushed in the clutch and held the brake. The RPM's dropped down so low I thought it stalled. They were going below 500 RPM's, the car would slightly shake like I stalled it, then catch itself and be okay. after driving about 50 miles, it seems to be getting better, maybe dropping to about 500 RPM's but not as much. Is this normal as the belt wears in, or should I have him re-adjust it all?

Thanks

you need to reset the ecu and do the idle relearn. Pull out the FI ECU fuse or the negative battery terminal after driving the car around to warm up. Put the fuse back, start the car, and leave it at idle with no accessories/lights/fan etc and don't press the gas. Let it sit there for about 10 mins. Turn off car and then back on to drive it around and let the ecu relearn the fuel maps. Maybe the place you took it to doesn't know about this.

You shouldn't have to reset the ECU if you just replaced belts, maybe something else is wrong.... maybe it was not at top dead center and the cam gear is off a few degrees where they installed the belt...

if its off even 1 degree, the car would barely run at all. Try the ecu first for idle issues. Then if its still there, maybe they didn't have the belt tension right.

The weird thing is it seems to be getting better from when I first drove it away?
If I just disconnect the battery after it's warmed up, then let it run for 10 mins w/o any accessories on, that's it?

ya and don't press the gas either. Just let it sit. I bet it will get fixed after that.

Well, after my 100 mile commute to work, seems like everything is worn in so to speak, and the idle is fine, actually running like a top right now....thanks again gearbox

Gearbox, I think you were exactly right. I still haven't done the fuel mapping, but in another post I explained the car was at the dealer for the headlight switch recall and to check out the electrical issues I was having. The first thing the dealer said was he "HAD" to fix the fuel mapping, the idle was off and needed to be re-learned. Thanks to you, I explained I knew exactly how to do it and he was pissed off. "well, your throttle body is dirty too and you should clean your injectors, you gonna do that yourself too", like it's such a big deal. I said yeah, fix the headlight switch and check the fuse box, that's why the car is there. They're such dicks............

how do they know the throttle body is dirty?

Anyway, good info Gearbox

^ I have no idea, would they even check that? My good friend is a head mechanic at a Land Rover dealer and he said they were just trying to "upsell" me. He was sooo f'n cockey with me, like I had no idea how to clean a simple throttle body plate?
They also wanted to do a "fuel injector service" yeah, 98$ per hour to throw fuel injector cleaner in my car, no thanks

Actually, the fuel injetor cleaning service at the Honda dealer here actually takes all the tubing off and cleans/ replaces it all the way from the second fuel filter to the injectors then take the injector off and gets the grime out. It's a good thing to do, but I wouldn't do it unless you actually have a problem.

^well that's different, but what's the time involved? a few hundred bucks at least I'm sure at that labor rate. it runs fine, don't know why they even mentioned it?

Not sure. My dad had his friend change his timing belt on his old Accord, and when the dumba$$ put the belt back on it slipped out of time and bent 7 valves. So my dad just took it to the dealer to have them replace the valves, and while the car was there, and the car was just setting there (the heads where being milled and re ground) the mechanic did it for free. I think my dad said it was about a $400 to get the fuel line cleaned, but the mechanic didn't charge him for it the mech said he did it so he would look busy and the boss wouldn't give him anything to do

^ that's cool, I wouldn't pay that type of cash for the service unless the car ran like crap. it's running good now, knock on wood

Gearbox, I need to rep you, did the re-mapping and it's idling so good.
It was going up to 1400 RPM's yesterday, so I did what you said and it worked great

Thanks again
