After having some troubles getting it to idle, and messing around with timing, it is idling, but when you give it gas it wants to stall. our timing light shows we are at 10 degrees before TDC and if you give it throttle it wants to die? 86 2.8L 4sp muncie Any help would be great!
Yep - the ECM adds advance. Is it bucking the starter when you try to start it?
Check your fuel pressure. Harbor Freight sells fuel injected fuel pressure gauges. 42 psi right after prime. 42 minus intake vacuum after it starts. The quick down and dirty test is to push the test valve with a screwdriver and see how high the gas squirts up. It should easily nail the rear deck lid.
Remember that is gas squirting up when you push that. Wear eye protection and don't start yourself on fire.
Your problem could be with the throttle position sensor (TPS). If you have a multimeter you can check for a smooth transition starting from between 0.2V to 1.25V at closed throttle and then rising to 4.5V as you cycle to wide open throttle. To do this, back probe the TPS blue wire with the red meter lead and ground the black meter lead. You'll want the engine to be stopped, and the key in the "run" position. If you get any other values or if it's not a smooth transition, then your TPS is faulty.
