ok... i originally had the problem about 3 weeks ago, i assumed it was my o2 sensor, so i bought a new one and replaced it. i also had a CEL and that went away after i changed it. i drove it around town real quick and it ran fine, didn't chug. i took across town a couple days ago and it dhugged a little but after that it was fine. today i drove it to my GF's house which was about an hour away and didnt have problems with it until i got to her house. we went into flint for lunch and when we were leaving olive garden it had a really weird whining noise, almost like a power steering pump has when it's empty. BUT, i dont have PS on my car. so that's ruled out. coolant is also at a good level. still no CEL through all this. on my way back just a little while ago, it started chugging again. and eventually it started losing speed, but maintained RPM's. it started chugging a little while later after i got it to gain speed again. i ended up stopping to get gas. after i got gas it ran fine up until i got into bay city and it started chugging again. and it has a new hesitation like it has a head gasket problem...(yay....) when i was in flint, it had a problem with idling really low as well. almost like it wanted to stall, but didn't... it didn't do that much, maybe twice.
out of all this mess. can anybody figure out whats going on? why would it chug after changing the o2 sensor. ? why would it lose speed, but maintain rpm's? what would cause it to idle low?
