Fuel problem - I think!
'04, 325i, automatic, 86k miles
2 Sundays ago, car had a sudden loss of power, couldn't keep the RPM's up. Of course, power went way down. After wife got home, I decided to drop it off at the mechanic's.
I don't know if it's the fuel or not, but I could not keep it revved up. Had a very hard time getting it up hill. It was the same feeling as when you're right at the point of running out of gas without of course running out of gas.
Mechanic couldn't figure it out - no engine problem, no tranny problem. Mechanic I trust. They've been working on my cars for many years. He's worked on the BMW before. He tested the fuel and said that the E85 that the wife filled it up caused the problem. He drained the gas, flushed everything, refilled with premium and the car ran fine - until today.
Same symptoms. If I can get it going, it will go with some chugging here and there, but getting it to start moving is nearly impossible. It wants to die. Got it home after some real embarrassing moments stuck at the lights and running some lights just to get home.
Here are some things, related? I don't know. Got into the garage and could smell burning rubber, as in a slipping belt. Don't know if it is a belt or not, I'm just describing the smell. I've been hearing what I think are some bearings chirping. I know that last year the mechanic said that my A/C compressor was way on its last leg. Said that the bearings and clutch were on the edge.
About a month ago, I had the manifold gasket changed and brake vacuum line replaced. Haven't had a full tune up since I've owned it (2007). Regular oil changes with synthetic oil. Matter of fact, I had the oil changed after that last repair and prior to when this issue started up last week.
Ideas? Thoughts? Things to look at before I mortgage my house to pay for repairs?? I'm pretty mechanical. I do most of the maintenance on our cars, when time permits.
