'86 951 Engine stalls when hitting bumps
Hi all,
Just got my first 951 2 week's ago.
The only bug I have is when I hit a small bump on the road the engine drops RPM to idle (900 or so), hitting the gas only makes it misfire and takes a couple of seconds to regain life... Once I even had to come to a halt and shut everything off and it started fine after. I saw that this could be caused by faulty wiring on the DME relay (relay itself is brand new). I have a modified MAF and a Huntley Racing ARC2-HR Air/fuel ratio calibrator/meter witch look like it is doing it's job...Someone told me that it could be a sensor that detect if the engine is being hit that would be at end of life and sending false info to the ECU(if you've ever been to Montreal, you know how our street's are: full of potholes after winter)... So before going into a long diagnostic on this, can you experts give me any idea's ?
Thanks,
