Manarius Posted December 4, 2006 Share Posted December 4, 2006 So, most of you probably didn't know, but last week I was having some issues with my car and I thought it was a MAF sensor So, tonight, in the middle of driving home from college, my car just decides to start acting weird. I was driving a long at ~55mph and I suddenly get a really bad shake from the engine area. Lo and behold, if I keep the RPM's up, the shake goes away, but under further inspection, it's just a cover up. I pulled into the grocery store parking lot I was headed toward, and I put it in neutral to rev it up, to see if it would clear out. Well, it didn't clear out. Instead, it just runs like crap. I can hear it hitting and missing and what not and during the neutral revs, I thought I heard it backfire a few times. Definitely signs of what my MAF did back a few months ago. It's weird because this was my 3rd trip (as in trip to one place) and it was in the middle of the trip that the car started acting weird. Before that, I was holding with an STi (he was making good time) and I had absolutely no problem (as in engine acting wacky). Is it another MAF? I have no posted codes, and I'm clearing the ECU tonight to make sure that that isn't the issue. Could it possibly be anything else? In the last shot, I replaced MAF, Knock, and CT sensors. So, assuming that all of those are good except maybe a toasted MAF, that doesn't leave very many sensors left to replace. ::EDIT:: Reset ECU and it's still hacking and crap. I really don't want to pay for another MAF - I don't think I'll get a deal like I did before. So, I replaced the MAF sensor today and here's what my car did:Freakin' a. So, I replaced the sensor - still ran like hell. Drove it back home - during the middle of the ride, the car decided to start running correctly again. Now, with the Hitachi sensor 55BCTurbo sent me, I have a CEL 49 code, but the car runs like it's brand new. Resetting the ECU has no effect on the code. Think I should just drive it around with the CEL on? Or is there a way I could trick the ECU into thinking it has the right sensor? Another interesting thing: My dad in his infinite wisdom wanted to make sure the car was firing on all cylinders. So what did he do? Pulled the plug wires at the coil to check the arcs. When he pulled the plug to #3, the car didn't do anything at all. Like, it didn't run rough or anything. When he pulled the plug to #2, it didn't run quite right, and when he pulled the plug to #1 or #4, the car ran like hell. Is that indicative of something? Thoughts?

nipper Posted December 4, 2006 Share Posted December 4, 2006 Pull a plug and no change means that there is a dead or weak cylinder, plug or wire. Time for a compression test. nipper Quote Link to comment Share on other sites More sharing options...
Virrdog Posted December 4, 2006 Share Posted December 4, 2006 Try swapping wires and see if the dead cylinder travels with it. Quote Link to comment Share on other sites More sharing options...
