Yes, the problem was resolved with the new wires. Thank you.

No. But come on, it cannot be that sensitive. It's working fine so far

No they are not leaking right not (not much to notice wet wires anyway) but they used to heavily before the head work. Does the oil shorts the spark? Funny developments: yesterday I decided to track the problem some more before doing the injector. So I erased the error codes, and they are not coming back. The car jerks, I drove it around but the computer says everything is fine So the P0303 was not even related... some old random fault. Well, the injector version is now obviously false. What I did yesterday is cleaned the ICV - no effect, checked for vacuum leaks (sprayed water everywhere) - no effect, replaced the fuel filter (who knows) - no effect, actually replaced the good tested plug wires - problem went away. I am not optimistic however, the same thing happened when plugs were replaced and when the seafoam was pored into the intake first time. We'll see; if id does not come back in 2-3 days, that's it, otherwise I'll just shoot myself :-\

That's what I was thinking. But the car worked just fine after head replacement for a long time now, I don't think it was screwed up than. Just got the call from the car owner, the car is running worse. (just pored a can of seafoam, in the tank this time, yesterday). She wants me to replace the injector tomorrow morning. I suppose will do that, along with maybe moving it around first to confirm the issue.

Thank you. Well, that's a lot of used parts, and since it's not my car... I think I'll start by moving injector around The plugs are OEM, wires were not replaced as I thought I tested them well enough (they are OEM too). Also, forgot to mention, the car had one of the heads replaced 2 years ago (I think the one with higher compression) and for some reason it always seems to perform normal again after I work on it, for a day or so, maybe it's just begging for attention

Hello there. I am trying to fix a car for someone, and it's one of those tricky problems: 2001 legacy, 2.5 AT. Symptoms - 1) car misfires at idle, at random, or more frequently so while barely moving at slow speed or in reverse. The misfire is random, more like a single shake once every while, not continuous. Also happens when standing at a stoplight. 2) it also often skips at hard acceleration (at different speeds while driving) - again single shake, then goes up fine, not all the time though. Codes: p0420, p0303 (the 0420 was there for a couple of years now with no issues). So, p0303 - misfire on the 3rd. What I've done so far: Did a "hot soak" by poring some seafoam into the intake. Replaced plugs, checked wires - no visible arching, resistance appears to be normal (3 and 1 lower than 2 and 4). Replaced the coil pack (used part). Checked compression - 195 on both at passenger's side, 180 on both for driver's side. What's next? Fuel injector? Do the symtoms somehow correspond with injector problem? Any suggestions will be extremely helpful. Thank you.
