I needed your help before and now we have a new issue. I have just about had it with the ongoing problems.
Mine is a 75, 2.0 with original FI. I dropped a valve seat and gave it to my garage to repair the head and replace all the valves. It all went back together and fired and ran but only for a very short time as all the cylinders ran rich and fouled the plugs. So my take on this is that it can't be the injectors as they are not all likely to fail at the same time. Perhaps it is something in the system that makes the injectors fire continuously? So could that be trigger points? If you could give me any ideas as to why all the plugs might foul I will start looking at each one until I nail it. Thanks Guys.

MPS would be the first thing I would check, along with its hose.
Fuel pressure would be the second thing. ....Actually, in my car it'd be the other way around, because I have a fuel pressure gauge permanently mounted in the engine bay... (IMG:style_emoticons/default/wink.gif) After that, I'd be looking at the ignition system. --DD |
