I am the proud owner of a "94" BMW 530i Sedan. About a month ago my car started to buck...right around 3,000 rpm's. I have a really good independent BMW mechanic I bring my car to for routine maintance. As the problem worsened I brought my Car to John Doe. He hooked up his computer and got a faulty code for an 02 censor...cool I says...just replace it. He did, but the problem was still there...$250 down the drain, but hey it happens...although it did run a little better. On one of the BMW forums I noticed someone having the same problem and was told to unhook the mass air censor...so I did and the car ran fine right away...was harder to start but ran great once started.
About 2 weeks later the I am on the highway and the car starts to run like crap again and eventually dies right on the highway. Won't start at all...I was about a $ 200 dollar tow away from my bmw mechanic...so I just had it towed to a local guy praying he would find the problem..(he said he has worked on bmw's before) so I figured what the hey...
Two weeks later my car is still in his bay...with a ? over the mechanic's head...so far he replaced the crankshaft positioning censor and that's it...I just don't know what to do...I could hope he finds the problem or just have it towed to my bmw guy. He did say it started with a shoot of ether fuel which tells me it might be a fuel problem...Someone said it might be a clogged fuel line...but the car would at least start...
If anyone can help I would apprciate it very much
