My '91 notch 4 cyl pings like crazy! Its been doing this for quite sometime since I bought it. I already replaced the timing belt because I thought that it may have skiped a tooth and i replaced the 02 sensor and that did not help.

Its got so bad that I've pulled the spout out so the computer cant advance the timing. It pings cold or hot and seems to really have no power at all. When the car is idleing its as if a motor mount is broke because it shakes so much, wtf??

what gives ???

compression check? after that a full tune up, check the timing aswell...what kind of fuel is in the tank? maybe a bad injector....who really knows? you gotta elminate the basics

Have fun buying a MotorCraft igintion mod for it :rolleyes: The Auto Zone brand runs 100.00 and MotorCraft out here is 250.00 :bang: I'm almost for sure I need one on mine but 250.00 is a crap load of money to spend:eek:
