E30 bmw bad ground intermittant bucking
\015 Intermittant bucking cant repeat it under a load or not. But cannot get it to buck past 3000 rpm ,when it bucks (1/2 a second) the mpg and temp gauge will spike just for that half a second.bucking can be at a take off or just driving any lower speed but no always ,take off fine 80% of the time! Cleaned connections at all sensors,crank sensor is fine coil tested good .believe it is a power issue ! HELP\015
I would check the battery terminals to see if they are loose...then have the alternator checked to see if it is bad. Is your Check Engine light on? I had a 97 corolla that used to die on me or act erratic when driving. I wondered what the problem was since it happened at varying speeds, circumstances etc. I decided to take it to a really bumpy road just to see what would happen...I hit one good sized bump and the car shut off. Found that even though the battery terminals appeared tight, the negative cable wasn't. Tightened it up and never had the problem again.
