Code Question?

[lscmkviii]

I did a search and found a similar problem on another thread with codes P0304 and P0308 #4 and #8 cylinder misfire. injectors are ok, C.O.P.s are ok, could this be an o2 sensor problem? CE light is on and blinks while accelerating. Also have 2 others....P2C29, I think this is a factory code but not sure? Something about Fuel Air Meter Aux Control? Next is P0634 PCM Temp high.....Dont know what thats about? Anyone had similar codes?

Is your battery new-ish? Alternator ok? I ask cause you getting codes from all over and these cars do not like low voltages at all. WHen voltage drops they get all fuzzed up and freak out.

Assuming everything is ok.... how did you check your COPs? You pull them out and inspect them for arch damage in the boot?

I replaced 2 of the boots and still got the code. I dont know how to see if it is arching? The #1 cylinder had a ripped boot but was running ok. The car seems to idle fine until it warmes up. The studder/hesitation is really bad up hills or on acceleration. When the problem first started I thought it was a tourque converter prob but it got worse and stumbles at idle, in any gear!

But did you replace 4 & 8 boots? I betting the boots are bad. They may not rip, but there will be a little carbon on them - like they got hit by electricity. If you feel up to it, maybe swap 4 and 8 to another locations, coil and all, and see if the problem moves. Dont forget to disconnect the battery.

Thanks UNITY. Problem seems to be solved. pulled all COPs and cleaned everything real good! Swapped the COPs around. No more CE light and no hesatation!
