My 1996 Caddy constantly idles from 1,700 rpm to 2,100 rpm.

Customer Question
Second opinion] My 1996...

Second opinion] My 1996 Caddy constantly idles from 1,700 rpm to 2,100 rpm. I�ve replaced mass air flow sensor, ics. Mapp sensor and new air filter. What else could this be? I even scraped 2/3rd of a coffee cup of gunk out of throttle body. Now what? Sometimes the engine will level off around 800 to 1500 rpm. I took it out on the interstate and drove it well over 80 and no problem. Help!!

Mechanic's Assistant: Does the engine stall right after starting? And what about hesitation or jerking during acceleration?

No. No stalling or jerking. Cranks fine runs well. Just Idels to fast after cranking

Mechanic's Assistant: What is the model of your '96 Cadillac?

It is 1996 sadden deville

Mechanic's Assistant: Are you fixing your DeVille yourself? What have you tried so far?

I do some minor things like installing the parts on the throttle body after I had the mechanic to put his computer on it. However, the check engine light comes on and goes off randomly

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I drive the car almost every day hoping it would level off. Performance is great. Just won�t idled down every time I get to a stop sign or red light. Sometimes it will go down to around 1000 or 1100 which keeps me puzzled

Thanks JOHN but I’ve already talked to two other mechanics with nothing new that I haven’t tried. I think I’m going to buy a new throttle body and put my new parts on it. This oughta do it. Thanks for offering your help but I’m asking for the 3rd time that my money be returned. Thanks
