My car will start and run fine when the motor is cold. But once it gets to normal operating temp it has no power and if I shut it off it will not start for 30-45 mins.

bad charging,sounds like alternator needs to be replace

maxteca

By no power I meant the car is slow.

KrayzieDxC

as in speed?

maxteca

Yes. Sorry I should have been more specific in my first post.

KrayzieDxC

what gas are you using? 87, 89, 93? try replacing your fuel filter , add seafoam in your gas tank. or just get a tune up.

maxteca

I did a tune up and seafoam in the gas tank and through a vac line last week. So I wonder if I loosened something up and its clogging the fuel filter or the cat. And I always run 91 in it.

the gas pedal is soft or hard? well my gas pedal is soft that means i have to push the dam pedal half way to get full speed.

you can check your throttle body if it dirty or not. if dirty clean it

otherwise just keeping seafoaming everyweek or so. i put one full bottle near empty and it last for a month with a nice acceleration, have you try seafoaming it in the break booster?

you should try replacing your differential oil to makes a good difference

maxteca

The gas pedal is hard. I put a full can of seafoam in the gas tank and a half of a can in the break booster when I did the tune up..

i have no idea, sound like to much of seafoam ,lol

fuel injectors?

maxteca

I just noticed that there is black liquid coming out of the tail pipe.

probably carbon from the seafoam treatment.
I would clean the EGR passage once again.

maxteca

I was thinking it was carbon.
