I changed the rear rotors/pads and changed the oil and filter tonight after work before I went home. The boss was around and was like, "your car is missing on a cylinder." I knew it had been running rough at idle for a long time but I didnt think about it cus I dont really care lol. I thought, "meh, its an old car. I dont care. I'm not gonna worry about it." Well... A little over a month ago probably I drove to Ohio and back which is about a 5hr round trip. It was a night drive and I noticed on the way there the car was missing every once in a while at highway speeds. On the way back it just kept getting worse to where the car would buck REALLY bad. It was late so I was gonna check on it the next morning. When I went to check on it, it didnt miss like it did before so I just dismissed it and said fuck it until it comes up next. It hasnt happened since then and right now its just idling rough. When you rev it up it doesnt seem to be a big problem. We pulled spark plugs and they looked ok. Ended up doing a compression test. That was some bad news and I didnt know that it was as bad as it was. The numbers were as follows:
Cyl 1 - 120
Cyl 2 - 94 or so
Cyl 3 - 73 !!!!! WTF?!?!?!?!?!??!
Cyl 4 - 94 or so
Cyl 5 - 120
Cyl 6 - 130
So... the engine only has 171k miles on it. The compression on a good engine should be around 140-150 and consistent in all cylinders right??? Pretty much something in Cyl 2-4 is fucked up. I could deal with all of em being 120-130. But 70-90??!?!?!?!!! WTF?! So... next week we are gonna do a cylinder leakage test and try and figure out what the problem is. I've officially decided... my car is a beater. It really sucks though because the week before Christmas I hit a van and I'm not fixin it ;) Now the engine thing. If its a big problem, I am just gonna find a decent used m20b25 and swap engines. Just lettin everybody know :) Sorry about the long post.
