2009 Pontiac vibe

Asked by Apr 03, 2017 at 09:52 AM

Question type: Maintenance & Repair

have a 2009 vibe. The problem I'm having is when
the car has been not running for 2 - 3 hours it is
hard to get it started again the only way to start it
is you need to hold the starter for a long period of
time .( I should say my check engine light is on)  
and throwing codes for 2 coils. Which I have
replaced all 4 and still the same thing. So I moved
on to maybe it's something else . So I replaced my
battery, alternator, all the coils, all the spark plugs,
fuel pump, and the coolant temp sensor. Still
nothing, and just recently when you stop at a stop
light, or start slowing down it will stall, and to get it
started again you need to hold the starter.  I have
been to different services tech's including my
husband who is a service tech and nobody know
what the problem could be. Help

It's the 1.8liters right? Could be the idle air valve, the throtle body could be dirty. Change the iac valve, reset the ecu, put the ignitionon for 10 sec, take the igition off for 10 sec, put the ignition on for 10 sec and start the engine. Let it run till the fan start, turn on for 10-15 sec long beams, a/c, radio, hazard lighs, rear defrost and shut the engine off. Could try this before buying the part...
