First thing I would do is head in to PEP boys or autozone & see about a free scan for any trouble codes.

    Does tailpipe show signs of running rich by chance? Black soot, like getting too much fuel? Try pulling a couple of plugs to see what they look like. (wet looking?)

2002 malibu will not start when cold. After it starts by priming it then starts fine.


ever tune it up, try new spark plugs. gapped to spec.
starts fine and runs fine, not said the latter....????

Cold starts are the hardest, takes
these things to start good. cold.
1: go winter fuel (if cold out, isit? then winter fuel works best)
2: a good engine and good spark plugs, (hot spark)
3: good cold start fueling,
to get #3 the modern car 89- now. needs a working and accurate
ECT sensor, this tells the ECU exactly how much fuel to use.
if the ECT reads warming than REALITY, the fueling will be weak
and may not start or stall fast.

no location stated, nor if car is a daily driver, that is fresh fuel
every week,,,,

My check engine light is on and I had it checked at


the iat sensor(intake air sensor) it is in big hose from air cleaner and has a 2 wire plug on it.iat sensor monitors tempurature of air entering engine. the pcm uses this info, to balance air and fuel mixture. if bad it can cause; poor idle when cold, stumble on cold excelleration, and surging when engine is warm. I replaced the iat on my malibu and it was less then 20.00, any auto parts store shold have this, I know advance auto does. the sensor just pulls out from hose.

Cold start


Obviously a sensor feeding wrong info to computer for cold start/running. Will save money in long run if you have it scanned for free at auozone, or PEP boys.

1996 cavilier runs great until it warms up


It may be the ignition module. You will need to check to see if you have spark to the plugs when
it stalls. If not the module may be the problem. You will need to remove the module and take it to
a auto parts store that has a tester that can check it.
