Spark plug gaps are very critical on computerised cars!! [some wont even start!]
distributor module may be breeaking down as temp rises they fail!
otherwise do compression check as it may have valve problems
also check plug leads & injectors aswell as the fuel pump pressure [ could bestarving for fuel]

Did you bleed the air out of the fuel injection rail? There is an air bleed valve on the rail on top of the engine. It looks like a shraeder valve you would find on a typical tire.

Im fixing what seems to be the same problem on my 92 grand prix try listening for a vacum leak when the engine is warm. my problem is the brake booster is leaking. when i come to a stop it almost stalls. i dont know if that will fix your problem but from my experience the grandprix's thats my guess. if im wrong look in the fuel injectors

My 2001 grad prix stumbels at acceleration once in awhile and in park sometimes there is no engine codes and i've changed pretty much everything plugs wires coils fuel filter and i even cleaned th


You did oxygen sensors at 100,000 miles

No exhaust leaks

No intake or evap leaks

Changing parts doesn't answer the question
Do you have ignition misfires

2003 Pontiac Vibe - 4 Cyl. 150k miles. Ignition coils keep going bad - every 4-6k miles. Coil 1 has been replaced 4 times, Coil 3 once. Coil 4 twice in the past year (20k miles). All spark plugs


Install new spark plugs, 4 new coils & replace the oxygen sensors

O2 Sensors are only good for 100,000 miles, then slow
down or quite

No idea why the coils do not last 5 or 6 years

Cylinder #1 is always at the front on a 4 cyl

Go to Rock Auto --Buy Wells Coils,NGK Double
Platinum Plugs & NTK O2 Sensor

Those parts are expensive because you have a Totota
Motor I guess

try checking the fuel pump. most fuel pumps have a filter on them in the tank if they get dirty or plugged it could cause the car to act up.

What are cord packs, and culd this be a problem why my 98 Pontiac grand prix wont start


coils packs are a set of 2plugs that are fired by one coil.so if you have a 6 cyl you will have 3 coil packs.its unusuall that all coil packs go bad at once.your no start could be caused by an ignition module,crank sensor,computer,bad connections,bad wiring,even a fuel problem.there may be a code set in the computer that may help to find were ot start to diagnois.it will have to be checked out to pin point the area.
