Engine starts fine and idles okay, but has no power, economy gage all the way in red, doesn't shift properly. Does not straighten out even after up to normal temp unless engine is shut off and restarted. Can restart after driving a short distance, and everything runs fine, economy gage in green, plently of power, shifts normally. Subsequent restarts even after a couple hours, everything works fine, but that first cold start. Happens every morning and problem never goes away until it's shut off and restarted.
Where do I look? Temp sensor? O2 sensor? Some vacuum control? EGR? How to diagnose problem?

sometimes it will,but lately it will not come out of park.

my 1990 chevy lumina 3.1 ltr v6 all of a sudden died on me while driving then it wouldnt start at all. the fuel pump works the starter works it has compression so i thought spark. so i wiggled the wires and there was some wires that looked a little burnt then all of a sudden the car would start when moving the wires so i bought new wires and a new coil pack and new plugs but now it still wont start. any suggestions

I reolaced the Throttle Position Sensor (TPS)and i think it need to be adjucted. I have not enought power on my nissan quest. also when i pushed the gas it stall and is does not changed geears on time

I checked fuses and do not see any that run the reverse lights. Parking lights and signals work.

The check engine light came on and I had it hoooked up to a computer. The computer stated that the bank one sensor one oxygen sensor needed to be replaced.

What are the steps?

Engine began running rough. Loss of power. Hesitating. Check engine light came on. Dealer says the Intake and Exhaust Valves burnt out, an internal failure. May also need a new cylinder head. Dealer says could cost $8,700. What gives? This was my 20 year investment! How is it the engine blew up/needs to be rebuilt? Anyone else experience this?

Misses when giving gas. Was able to spray MAP cleaner inside dist would run fine couple days later will start missing again. any ideas

Cause I drove into a parking lot, a check engine light came on and it died.
Scanned for codes. 2 came up as interesting. 1)Knock sensor 2)Camshaft sensor.
What would have to be replaced on the car?

then the noise stops when i go of 10mph.

It doesnt matter if its a fast or slow idle, when the lights are turned on,the car dies, if the brake peddle is depressed the car dies. After it dies the wipers come on.

code came up PO136 O2sensor bank1/sensor2
