on idle the car misses, a lot

[danny_l_2005]

So on idle the car misses, a lot. It is weird because I doesn't "feel" it misses when going partial throttle or at WOT. But during deceleration I feel the car jerking because of it. Now I just tried new wires to see if it fixed the problem but it doesn't. Now my question is, will a bad o2 sensor cause this? Or a changed base timing(I don't know its base timing)? Or maybe wrong cam timing ? As i see the timing belt the cam gears seems to be way off timing, or maybe its me (as I haven't change a timing belt before). I'll take a picture to show you what im talking about.

this sounds obvious but are the plug wires on the right plugs?

When i put a new timing belt on my car it did the same thing. It would run fine except it wouldnt idle. It idled like it had a high lift cam. It turned i set the cam gears 1 tooth off since it is hard to get them lined up perfectly by yourself when you put a new timing belt on. It is possible to do by yourself, but i found it much easier to have someone hold the cam gears in place while i set the timing belt.

Check the timing, boost leaks, and the plugs.

Wiring is right.Its
4123 coil
4321 motor
Plugs are fine, I just recently changed them to BPR6ES. Wires seem fine as I put my 2g plug wires and didn't fix the problem. I'll check for boost leaks this weekend, even though I high doubt its that because even with this misfire in idle... the car pulls pretty good. The transfer case is locked up and is getting fixed next week thank god because being fwd on std sucks... I can burn rubber all the way to 3rd

^ you gap the plugs right?

 

[danny_l_2005]

Yup. I have always gapped my dsms with .028. I'll come back with more results during the weekend. Expect a picture of my cam timing.
