I have a 93 960 with 114,000 miles on it.
After it warms up, the engine misfires while driving at a speed of 35 to 60 mph. Before it warms up it runs like a charm.
So far I have replaced the o2 sensor, the rubber intake hose between the throttle body and mass air flow sensor, the mass air flow sensor and it still misses.
Is there anyway of checking the ignition coils without acutally replacing them?
I have had it in the shop and scanned, no codes come up.
My next line of attack is to replace the plugs.
Anybody have any suggestions?
Thanks
