Damnit.
After doing more research, I've definitivly ruled out the maf from WOT misfire/backfire/hesitation
etc. The EEC IV reverts back to pre-programmed spark and fuel tables and ignores the MAF
at full throttle. On later 94-95 cars with EEC- V the MAF IS refrenced at WOT....So>>> I'm now thinking
ignition crossfire? (spark plug cables could be damnaged and now have too much resistance??
But for this to just *BAM!* happen one day when I turn the car on makes me think....it's
not the wires....I'm going to check
the primary/secondary restince on the coil and see if they are withen spec....Maybe the coil went bad???
Okay, so rewind back to 2 weeks ago....Car was driving proper....One day the motor just shut off
(see this thread...) anyway a connector had come undone on the fuel pump in the tank.
I fixed it and everything was fine...For about a week. (could this be related?) SO then I was trying to get the idle
speed/quality fine tuned. I decided to unplug the ISC motor and set the idle to 900rpm.
Then I unhooked the battery and let the car sit overnight. In the morning I started it
up and forgot to plug in the ISC connector. I drove it for a block or 2 and noticed the idle
was hanging up at 2500rpm. I remembered the connector and plugged it back in with the engine
still running. EVER since then the performance has deterioited to the point where I dont
want to start it untill I get the new MAF to try. But what the **&^% I don't think this is going to fix
the car.
SO>> What now? How can I test the magnetic pickup in the dizzy? If the maf dosn't fix it, and the
magnetic pickup/coil/new wires also dosn't fix it....Fuel? I don't have a FP gauge in the cowel, only
mounted on the fuel rail. So I cant tell if there's a pressure drop/spike going on at WOT....hmmmmm....
Anything else? Should I do a compression test? I dont have the adapter for my gauge, but it's prob. cheap...
Let me know if any other ideas come up....
