- was hoping i can get an answer so i can fix this issue. This morning i used my car to the store and it started with no problems then about 2 hours later i started the car then it died out i tried to start it again but it took a couple of seconds then it started. would any of you know what causes this problem?
I had a similar problem in the past. Started the car, and then it stumbled and died. Crank..crank.. crank.. finally started.. rough idle, then smoothed out. Does this sound familiar?
It was a dirty throttle plate/body throat. The gummy varnish was preventing the throttle plate from opening, since the computer uses this to idle the engine. If the throttle plate cannot move as the computer commands, it gets confuses and the engine dies. There is a hole on the backside of the throttle plate area. That is the hole the throttle body uses as an air-bypass for idling. This replaced the older idle air valve that was used on older engines.
check the throttle plate, both sides. How to do this? I don't like forcing an electric motor driven plate, I have someone turn the ignition to on, then have them push the gas pedal down, plate will open.
Check that.. let us know.
EDIT: forgot to say the obvious.. if it's gummed up, then some CRC throttle body cleaner or maf sensor cleaner is in order. If you use the throttle body cleaner DO NOT spray it down the throat of the throttle body!! Because we have a plastic (nylon 77) type intake manifold, the acetone in the throttle body cleaner WILL melt that plastic! If the OP already knows this, it's for the newbies to read. Spray onto a clean rag, then clean with that. Or can use MAF sensor cleaner (always safe for plastic, quick drying) for the not as gummed up deposits.
