Car running weird and doing weird things..

[91CoupeMike]

After I did my tune up, all new ignition parts... The car ran great and the best it's ever ran.

But for the past few days, my idle has been low (500-700rpm) and sometimes surges to 1000 and back down.

Just today the car feels powerless. No low end torque. Just a real turd.

Say from 2500rpm in 2nd it will bog and hesitate to build power and get going.

Just now I was seeing if it was running better after new gas in the tank.

I was in 2nd and just hammered it to 5000-5500 and it just fell on it's face. No power, car went quiet then it started to run normal again.

This has never happen before, it was almost like it ran out of fuel. But fuel cut off is over 6k.

The car runs fine when it's cold, but once it warms up it's a turd.

The idle issue I believe is a IACV and I'm going to clean it and see if it helps.

Any other suggestions on what is going on?

maybe you should stop working on it.

maybe you should stop working on it.

I would like too, but shit keeps going wrong.

I do good work and always make sure everything is correct. I hate half-assing.

The only time it's ok to n-rig something is in an emergency and I've never had to do that.

The power loss issue I should be able to track down, it's the cut off before 6250 that is throwing me for a curve.

Almost like it went Into limp-home mode or something. Very odd.

what kind of plugs did you get, did you get new plug wires if so make sure you have the firing order right, make sure you have wires fully connected, check and see if you got a wire on the manifold or something and melted it

New everything. Motorcraft 450 plugs. Gaped to 45 thou.

CEL bulb is out. I need a digital obd1 to pull codes.
