1988 22re timing problem

I have a 88 pick up with a 1990 22re in it. I am having a hell of a time getting this thing timed so I can go smog it. I cannot get the idle low enough to time it. I got it set between 5-8 degrees . When you give it throttle it just falls on it’s face. The timing reverses rather than advancing with throttle. Purrs like a kitten at idle. No vacuum leaks. Anybody have any ideas

Welcome to the forums!

When you set yer timing, did you jumper the round connector attached to the fender wall so it could be timed correctly? What is yer current idle RPMs? Is the check engine light on? If so, what were the code(s) pulled? How good is yer TPS?

It would seem that air is gitting into the intake system...which means you have a vacuum leak. Try using an unlit propane torch with a hose attached to the nozzle so you can direct the propane around the various points. Start the engine and take yer time probing with the propane hose. I think you will eventually find where the vacuum leak is at.

How good is yer PCV valve and hose?
