While at a stop light engine cuts off.

This sounds like a bad IAC unit,cleaning want help it.

I was afraid of that.

Check engine light never comes on either.

The IAC want throw a code.

Have you checked real good for vacume leaks,?

Yes I have checked good I even replaced several hoses just to ease my mind. Could the tps cause it along with IAC?

A TPS would make engine light come on,and throw a code,that is why i say bad IAC.

It idles good some times its really annoying to trace down the problem. I'm at wits end

Oh ok, I'll buy one after the holidays everything closed this weekend

I have another suggestion but let's go with T_S_T recommendations for now.

What's your idea?

Well since you have already cleaned throttle body and put in fuel injector cleaner and may have done this already but take your vehicle out on the road and hit the passing gear a few times that will help the injector cleaner clean the fuel injectors better and also help remove any gum and carbon build up. Just be careful no speeding ticket.

Lol yes I've done that plenty. I have a heavy foot. I was even think of the cats being the problem. But I'll try IAC first .

Does its shut off coming to a stop or when your are completely stopped ?

If it was a clogged catalytic converter you would also have loss of power vehicle not being able to go over 25 - 30 mph. If it cuts off coming to a stop you may also have a bad ( Toque Converter Clutch Solenoid ) .

It runs and drives great it just cuts off at stops but it starts right back up.

I hope its the IAC I'm going to buy one when the parts house opens back up Monday morning.

Turns out IAC and the tps fixed my problem thank you so much guys
