This car is trying my patience but I will win! As some may remember I bought this car cheep and have done lots to it clutch, dash, exhaust, rear end...on and on. Now that I have all that stuff done I'm dealing with drivability issues. Here's what I've got...

The car starts and runs ok, After it's warmed up it would stall after it was reved up. The IAC motor solved that problem. Presently if you reve it up it has a flat spot or hesitation off idle and has a mild skip. The car goes like a banch full throttle. The car is very difficult to drive off from a stop. If you don't slip the clutch it imediatly heasitates and will stall. The skip is probably an injector. I was hoping to drive them clean with a fuel additive. Cap rotor and wires are all new. Cylinder balance checks out good. I'm thinking throttle switch. Anyone had an issue like this?
 
Get yourself a new TPS (Throttle Position Sensor). You have a dead spot on the curve. A very common problem.

I thought as much. Thanks for the comeback1 I'll order one tonight from MAM. I should probably make life easy and get the harness to set it up too.
