first startup flat throttle

[Bradley G]

It has occurred only the moment I start the car.
A couple seconds after it starts, I go to blip the pedal and it is flat, no blip.
I wait a few more seconds and all is fine.
The car has done this consistently for a week.
I got a gas filter, new plugs, and I"ll clean the air filter and the T/B see if it stops.
Feels just like my SHO did, when the crank sensor went bad.
Except, it only does it once or twice when first starts.
Anything someone cares to share if it happened to you or have another Idea?

If you think it's the CPS take it off clean it and reisntall it. I'd also take the maf out and give him a good blast with electrical contact cleaner. Lastly - seafoam the intake.

Just guessing here Brad, but i'd check the voltage at the TPS. It should read steadilly up to 5 v as you slowly crack the TB open. IIRC, it's the top and bottom wire you backstab in the harness.

Thanks guys, I'll try those things you mentioned.
