Michigan TD troubleshooter?

Is there anybody in the area that can help me troubleshoot my car? The list of problems is long, I need somebody to help me check cam and ign timing, and whatever else may be wrong such as bad sensors or something else that I don't know to check. I have an 88 Shelby Z with a 2.5 cb T2 turbo and wire harness. T1 auto smec. I feel stupid asking for help with this but I don't know it all and I don't wanna mess crap up by doing something without knowing what I'm doing. If you are in the area and have any questions feel free to text me 586-563-7485.

I may be able to give you a hand next week sometime. Does the car run right now?

yea it runs just has a lot of popping on decel and at idle. At the sdac meet I heard the guys 2.5 t2 shadow. I was sooo quiet. Thats what I'm aiming for

Ok so I attempted to set the timing. The timing mark was bouncing 2-3 degrees in either direction of where it was supposed to be. I assume the timing belt is stretched causing the issue. Any thoughts?

that was with the coolant temp unplugged right?

yes sir

It can also be play in the distributor or gears to it on the intermediate shaft. Generally, not a huge concern. If it was a fresh rebuild and everything new you could say something was screwed up. But on a well used engine, a couple degrees is almost normal.

If you want to check cam timing (and it looks like you have a timing light), set the distributor so you are at 0 degrees advance (with coolant sensor unplugged) and point the timing light into the hole in the side / top of the cam timing belt cover. The small hole in the cam gear should be centered in the cover hole.

The engine is pretty fresh. Its a 2.5 out of a high school training aid that had something like 100 miles on it. I am wondering if it was the Timing belt practice engine though.

I was thinking that...I guess TJ told ya about my motor? or did I?

pull any codes?

you did.

The only code I got was tps sensor and coolant sensor. Tested TPS and it was fine. Code eventually went away. As did the coolant temp sensor. Its been a little over 1.5 years since I had the timing done. If the dizzy was stationary. What would cause it to be 12-14 degrees off?

Ok heres all the troubleshooting I did so far. I took off the top timing belt cover and checked tension and alignment. All is well as far as I know. Ignition timing is still somewhere between 10-14 degrees. Plugs wires cap and rotor are all good. What else could make my timing be somewhat erratic?

Have you tried another timing light?
