already done, i think it may be the wires i noticed a few spots that look worn. How they got worn i have no idea. They are probably about 2 years and 40,000 miles old, so i might just replace them

Even if the wires didn't look worn, replacing them would be my first guess in troubleshooting your problem. So in your case, definitely go ahead and do that.

It was the wires.

Soooo much smoother now.

Enjoy!

FAWK!!!

It's still there!

here is some more info on my recent repair history here:

BTW had the fuel pressure checked:

60psi engine off
55psi idle
65psi at 3000 rpm

If anything that seems too HIGH.

Also, one more tidbit, it seems to happen once the engine is warmed up.

For an SVT the pressure should be
45psi at idle, 55psi at WOT, + or - a bit.

I had a fuel pump that when the engine got warm the pressure went down not up.

Yea, how big of a problem is too much fuel pressure?

Could a bad pump, pump too much gas?

But it still seems like the engine is NOT getting gas, not getting too much.

Weird.

Not the coil pack either....

This is gettin annoying as hell.

Fuel pressure regulator? Any codes?

The PCM is supposed to compensate for higher PSI and bring it down to normal levels from what I've read.

I looked up a P320 and:
Continuous Memory Diagnostic Trouble Code (DTC) P0320 indicates two succesive erratic Profile Ignition Pickup (PIP) pulses occurred resulting in a possible engine miss or stall.

Possible Cause:

-- Low battery voltage.

-- Loose wires/connectors.

-- Open/Shorted circuits.

-- Damaged distributor cap, rotor, plugs or plug wires.

-- Damaged coil, ICM or PCM.


There's a whole diagnostic sequence, but it's too much to put here. Get a Service CD and run all the electrical tests for a P320.

I hope you don't have a damaged PCM. If so wreckers are the best place to get one. I got one for $75.00 cdn

I have a service cd but i don't know how to navigate that damn thing.

Well it's not:

Plugs
Wires
Coil


So to me the ignition system is fine. So maybe a bad pcm? or a fuel delivery problem? or what else?

It seems to only happen when the car is warmed up. However it took me 8 starts to start the thing this morning(never had a problem starting b4). But once it started it ran like a champ until it got warmed up and then started freakin out again.

I'm lost.

On a more positive note your engine sounds sweet

Well it wouldn't start this morning.

Cranked fine but wouldn't catch.

So i'm replacing the crank sensor here in a few. We'll see what that does. I also have a Camshaft position sensor coming tomorrow just for [censored] and giggles.

Is your car chipped?

Strike that. Reverse it. I actually had the cam sensor and the crank sensor comes in tomorrow. However I am 95% sure I have found the cause and it IS the crank sensor. I will have to wait till tomorrow to know for sure. But here's the scoop:



Seems that when i had my crank sensor replaced 2 winters ago they broke the clip on the wire harness and used some sort of blue goo to hold it together. When I replaced the 02 sensor last week I must have pulled it loose. This sensor itself is probably still good but I am gonna wait on the new one anyways.

It does leave me one problem. Since the part that's wired to the car is the broken piece, how am I going to keep this thing held together. Electrical tape? Duct tape? Any ideas?

P.S. No my car is not chipped.
