having some issues with my 2.2 GT

At idle and when at half or less throttle it runs absolutely normal.

When appyling more throttle - about where the second valve opens in the throttle body and the accelrator pedal goes a little harder - it starts to sputter and hold back. Actually feels like a cylinder is not firing at all.

It runs all the way to the red line with no problems when only using half throttle, so I dont think fuel starvation is the problem. Also I have been running for app. 45 min. tonight with no problems (except the full throttle issue)

I changed all plugs, plug wires, rotor and dizzy cap in the spring, and the car has allmost not run since. Problem was there before aswell, though it seems more pronounced now.

Could it be some vacuum leak, a bad fuel noozle, fuel filter (4-5 years old) some electrical issue, or where should i start?

Feel a little lost here, so any help would be greatly appriciated

One final thought: Could it be condensation in the fuel tank ie, water in the fuel?

What plugs did you use??

cgtdenmark

but they were bought at a local parts speciallist together with the plug wires specifically for the car, so suppuse they should be ok.

Problem was there before the plug change aswell

power "full-idle" issue kinda sounds like a clogged cat. to me.
