Hey everyone I've searched all over the forum but am coming up blank.

So here's where I at...
Last week I did my head gasket and timing belt kit on my 02 civic w/1.7, now that everything is back together I'm staring to have an issue. It starts up usually on the second try after started it runs great and could run forever but as soon as I give it a little gas it it studders sometimes stalling out. If I give it more than half throttle then it's fine and I can drive it down the street but it I need to accelerate even while already moving it starts cutting out.

I've checked for vacuum leaks and I'm not getting an cel lights.

Any help would be much appreciated

check compression,

check timing marks, you could be off by a tooth

And check the ground wires....

Thanks guys for getting back to me.

Mikey is there a way to check if My timing is off without pulling the right side of the motor off again?

I think the ground wire would be more of a constant issue wouldn't it?

you will at least need to remove the top half of the timing cover to see the cam marks, then you can use the marks on the crank pulley and bottom timing cover to align the crank pulley to TDC

You tell me.
If a ground wire was attached to a loose bolt--- and lost contact SOMETIMES--- could it cause your complaint?


If you just did the timing belt and head gasket and NOW you have a NEW problem, you need to retrace every step you made, as you probably caused the new problem.

In the pic, the eyelet on the left is the main ground circuit for the PCM and most of the stuff it controls. It's THE most important ground for it.

Okay I have checked the timing and brushed up the grounds and still I am getting the same issue. The timing was off by a tooth, so I adjusted it andI also noticed the PCV valve was no good so I replaced that as well. I but new plugs in too prev owner had bosch I put NGK in. I'm really lost on this one because it drove fine before the head gasket and now I cant seem to figured it out. Any more suggestions?

mikey1

then its obviously something you have done,

did you check the compression?

if so, what were the results for each cylinder?

if you have not checked compression.....do so

how exactly did you check and correct the timing?

my money is still on the timing or a compression loss....one or the other....maybe both

Jmareiro

I haven't check compression yet I dont have a compression tester.

As far as timing goes I took the top cover off rotated counter clockwise till the top gear was what I thought tdc. Then I looked down and noticed that the crank pulley was not lined up. I then took the pulley off and bottom cover then relieved the tensioner and moved the crank in the direction it needed to go. re set everything and made sure they lined up started it and rechecked.

What puzzled me was the fact that nothing changed from moving it I assumed it would have either ran worse or better not stay the same.

Are you using the correct set of timing marks?

Is it still a tooth off, maybe the opposite direction this time?

mikey1

get one, you need to verify compression

what mark on the pulley were you using to verify this?

what marks were you using to verify this?
