2002 Pontiac Trans am V8 5.7L.
Service Engine Light Transmission was flushed Standard. Fuel injectors
cleaned a/c compressor replaced.
Question = I just started the Car and started to drive when the service
engine light came on and started flashing. The car starts to shake in first
gear and 6th gear really bad. Any ideas. Thank You so much.
KK:
A check engine light that is flashing is an indication of a dead misfire. Te
SES flashes because the misfire is bad enough to cause possible catalytic
converter damage. This is the only reason for the light to flash. Common
cause for a misfire on this engine is a bad plug wire, spark plug, ignition coil,
or injector. With it missing badly in the higher gear, is would suspect one of
the ignition components listed above instead of a injector. In a high gear
and giving a little gas to say- pass, this puts a heavy load on the ignition
system, and would cause a misfire. Spraying water on the coils and wires
may cause the spark to jump. You would be able to see and hear it. This is
a way to determine which cylinder is misfiring, if you dont have a scanner to
read data.

Repair work done prior = multi spark replaced
question = my check gauges light goes on ONLY in drive when I'm stoped..i notice the oil

@ the same time when I'm stopped & the check gauge light goes on..when I'm driving or put it in

OK, so 2 problems.
Either of which will turn on the check gauges light.
The engine has oil pressure. That why the gauge goes down, and turns on the gauge warning.
The engine is also overheating if the gauge goes up too high. This will also turn on that warning.
Need to find why low oil pressure, and check coolant level. May need a thermostat for the
temperature problem.
