I've replaced and done alot of work on my 95 5.0, and my main problem is ignition timing, so i unplug the spout, I know it calls for 10 btdc which it won't run because of the cam and other aftermarket parts. So I bumped it up to about 17 btdc with the spout dissconnected, and it runs good. Idles great, sounds great, and will rev to 5.5k or so. As soon as I plug the spout back in it wants to die, and when you try to rev it up it revs to about 2.7k and acts like its hitting a rev limiter. It has not had a tune done yet and that may be the problem, but I'm afraid to drive it with no spout in for risk or pre ignition or detonation.

new oe forged rotating assembly, trick flow stage 1 cam, 1.6 aluminum rr, gt40x aluminum heads, longtime headers, accel new dizzy with plugs and wires, 24lb injectors with a new maf with it. Let me know if more info is needed.

 

if you go easy on the car you should be fine, just don't lay into the skinny pedal if you can avoid doing so, sounds like (to me) either you need a tune up, or the spout may be going bad??


are you getting any check engine light?
have you pulled the codes?
have you cleared all DTC/codes that are stored??

 

I have had check engine lights on, I've forgotten what they were though. I just wasn't sure why when the computer advances the timing it won't run. So I didn't know if anyone had ran into this problem. Thanks though!
