03 impala issues
03 impala bought 2 years ago and was fine
for the first year and now it's been a
guessing game for what's going on with it
been to 4 different mechanics and none can
tell us what's wrong here's our issues:
Starts fine on the first start but then it's
stutters when trying to start..have to put foot
on the gas pedal while turning the key to get
it to start most of the time and when that
happens we get a rich fuel smell inside the
Stalls just randomly whenever under 30 to
40km so come to a intersection it'll stall and
gets arm strong steering.
Sometimes it doesn't wanna move when
putting foot on the gas and when it does go
Anyways just wanting to know some ideas
or of anyone is having same issues others
are.pointing us to the crankshaft position
sensor but just want to make sure is all.
Thanks for anything advice
If you smell fuel and shakes when under load, i would suspect the ignition, a sparkplug coil(s), sparkplug or even maybe an injector (less of a chance). Any change when humidity in air? Any codes/missfire?
Starter has been changed spark plugs have been changed and nope no codes or nothing and no humidity at all
Did you change the spark plug wires along with the spark plugs? You should have. Try cleaning the throttle body and IAC (Idle Air Control) valve. Sounds like the IAC is misbehaving or possibly the throttle position sensor. Check the coil packs as well. If you find one that's weak, replace all three. If one is failing the other two are soon to follow. HTH. -Jim
