08 sebring touring after changing throttle body why would my car still idle low and sputter when stopped at red light?

Hi
your description of the car problem indicate that you have a problem in throttle body

have you do any maintenance recently to car throttle body, or the problem come suddenly. if no.

if no maintenance done then i suggest to inspect engine intake
line ( from engine filter box to throttle body) for any looseness of damage, also you have to clean your throttle body by an experience tech. and perform idle learn procedure.

hopefully this information fix your problem.

best wishes

Go to your local auto parts store and get a free OBD2 diagnostic scan. Guessing can cause you to fix something that isn't wrong.

You have an air leak around the throttle body

sounds like a fuel problem. when was fuel filter changed last! if filter is ok, remove and clean the idle air control it may be sticking. this is what controls idleing, on todays cars. ( IAC ). good-day ! there is another thing you can do. clean out around throttle plate of throttle body and make sure aircleaner is ok. this should help!!

It depends on the car. If the car has alot of load on the transmission going uphill, it can make the car gobackwards. Many reasons. Weight, what type of car etc. It isnt something I'd worry too much about. Just have your foot on the brake when you stop

Replace the Idle Air Control Solenoid. You will have to relearn the computer once you install it. Not a big deal though.

clean the IAC. Use spray carb cleaner and spray the idle air control valve. It is on the throttle body near the throttle plate. It may have become stuck with deposits.

Clean the throttle body as well. Check for vacuum leaks

I don't know what the STP cleaner may have done; I had a similar problem where my car would idle very low when stopped or in a drive-through waiting. It turns out there was black soot on the engine intake. I disconnected the rubber hose from the air filter at the engine (take cover off, loosen 1 clamp). I used a spray can of throttle body cleaner and wiped the area clear. I then had my dealer perform the programming change for a service bulletin that mentions throttle body coking.

check your transmission fluid,the motor will stall when fluid is low

you could have a faulty Tps(throttle position sensor) this is located on the throttle body and has either a 4 wire plug or a 2 wire plug. I'm willing to bet that you need to replace this. the tps is responsible for your idle setting via the ecm(engine control moduel)...please rate this
