Heya guys, have an '88 N/A. Just got it running not too long ago, tried to get it moving today. It starts up right away every time, although runs a bit rough, and I was able to rev it up slightly (the highest it would rev was 2.3k and the revs wern't very responsive vs the pedal). She idled a bit, died, idled a bit, died, then by the end, she would only start, and pretty much as soon as it started, it died.

Fuel pump is directly connected to power, i just put a few gallons of fresh gas in it. I just need to move it to my garage so I can start tearing it appart, maybe a few hundred feet.

I'm used to shitty idles on V8s being vacuum problems, but this sure as hell isn't a v8 :P Any help would be appreciated.

Vacuum leaks are a good place to begin. You can also set the TPS's Green/Red wire to 1 volt w/key to on after the engine is as possibly hot as it can get. The fuel filter, fuel pump sock,injectors might be a bit clogged. You also might want to check the Water Thermosensor and at pin 2I of the ECU (Green/White wire) it should read 2 to 3 volts cold w/key to on and eventually drops to .4 volts completely warmed. And the catalytic converters could be clogged. And the ECU/engine grounds could be rather poor.

I cleaned off all the grounds, sprayed some carb cleaner around all the vacuum lines i could find, no leaks detected, and checked fuel filter, they're all good. I don't think the cats are clogged either, she's smoking quite well out of the tail pipes :P

I got it idling again after letting it sit for a couple of hours. Still not responsive on the revs. It idled though, and I put it in gear, it engaged. Every time I tried to rev it up, however slightly, she dies. I just wanna move it before the snow gets here so I can drop my 5.0 in it! haha

Can't get it warmed up, but I'll set the TPS when I get to it next. What does this water thermosensor affect?

The amount of fuel injection flow relative to engine temp. The engine ground is under the uim and bolted to the engine housing.

How long was it sitting when I buy old cars they can sometime have stuck seals still run but horrible compression test is always good if low comp try some tranny fluid down Mani crank over with no ignition let sit overnight sleep :-) come out start up and smoke the neighbors out trick from my o.g. s :-) I was in hurricane sandy trust me I got plenty of seals loose from salt yeah I did it still running after flood :-) :-)

if its a few hundred feet and your pulling it all out just push it or tow it.

find the variable resistor and turn it clockwise until it stops.

sounds like a fuel pressure issue or possibly a bad TPS.
