Message Ive read alot.

My car runs pretty poorly, but when its cold it seems to run better. The longer I drive, the worse it runs. The only code im getting code 34 DET sensor.

When I start the car, withing 90 seconds of driving its fully warmed up according to the gauge. And I think my car overheats, but the gauge never gets to half way, once it got up to 3/4 and was running like absolute crap.

The only thing I know is not connected is the AAC or AICV (not sure) When it was plugged in it idled too high, I followed the adjusting procedure and everytime I put the connector back on it just Idled too high so I left it off.

I replaced the pass PCV, havent got to driver yet.

Im stumped, the only other symtoms that indicate problems are the fuel pump buzzing after the car is shut off, and extreme heat under the hood.

I always run good gas in it, and im not too abusive. The car just dogs when it gets hot, to the point where it doesnt want to maintain speed and just makes noise without accelerating. I had a new clutch put in and it didnt help at all.
