Exclamation Timing question?..

Have a stock 1988 mustang gt 5.0 5 speed. The vehicle is completely stock with the exception of a sound system and a full exhaust(headers, pipe and mufflers). At idle it is anywhere between 1100-1200 rpms but if driven around for about 45 miles or so it will stoke times idle at 1400rpm all the way up to 2000 rpms after a complete stop at a light. Is my timing too high? I didn't see any part of the cable stuck on anything or anything like that but my last foxbody which was a 5.0 but an lx idled at about 900 rpms. Is my timing too high? What should it be set at because it seems like it's just going through gas. Thanks again.

I'll use an ohm meter to figure out the voltage and adjust it. Let you know how that goes.

Run your codes.....why, cause it's free and might give you an idea of what's wrong.


Secondly clean the IAC.


Clean the MAF.


Check your grounds.


Check for vacuum leaks.

What should I clean the iacv with?


Don't have maf 88 came with speed density unless it was a California edition other wise it wasn't until 89 that maf came into play.


Grounds are good


Will check for vacuum leaks and I don't have a coder, how do I pull codes without obd1? An no I do not have a check engine light either.

Google it.
You can use a jumper wire on the test connector and the codes will flash on the Check Engine Light. No code reader needed.

Lol.
Yes. A paper clip can be used. Just don't let it touch any metal while you are doing the test.
As for the diagram... GOOGLE IT!!!

Haha.
There's also some YT vids that show the procedure. If you have some codes, the hardest part is to decipher what the light flashes are telling you. Take your time and pay close attention to the time intervals between the flashes. Watch it go through the cycle a few times if you have to. It's pretty straight forward.
Good luck!
