Could be:

o2 sensor
ect sensor

Has this thing been tuned up, ever?

 

[jeffrey kennedy]

No tune ups ...I no after the car heats up and is cut off and you try and start it back its like it gets way too much fuel

Also there is no check engine light ...

Does your CEL work?

I would suggest doing a tune up first before anything.

 

[jeffrey kennedy]

Yes the cel works ...I did change the plugs out and that did not seem to work ...if I shut the car off and start it back asap it starts fine ...it only acts crazy after the car starts cooling like maybe 5 mins of sitting...I used a can of sea foam hopeing it would help...

Did you pull the O2 sensors before running that seafoam through? Keeping them in is a sure fire way to destroy those sensitive sensors with all that crap running out of the exhaust.

You need to change more than just the spark plugs. Full tune up. Wires, cap, rotor, fuel filter, air, oil, pcv if equipped, valve adjustment, etc.

Did we not just have a situation like this about a month or 2 ago?
