1998 Pontiac Trans Am, 5.7L. My driver's side front turn signal isn't flashing, when i flip the switch on the steering wheel column the light on the dash shows up, but it does not flash, and as i go outside of the vehicle, the rear taillight stays lit up, and the front turn signal stays lit up, but as soon as i flip the switch back, the light on the front shuts off, even while running. Want to know what part I'd need and how i would fix it. Thanks and i appreciate your answer
JK: Sounds like a bulb, or socket problem. Have seen bulbs do weird things. Turn on the passenger side signals, walk around the car and note all the lights. Make sure when using drivers side, all lights are the same as pass. side, possibly will tell you where the problem is. Could be an incorrect bulb, 1 bulb dead, or a socket shorting out Need to compare left and right sides to find what area to concentrate on.
2001 Pontiac Grand Am 2.4 L Changed spark plugs Work done to repair this problem = changed spark plugs GM tech = JK question = The car intermittently misses under normal driving conditions every once in a while. Changing the spark plugs makes it go away but a day or so later it comes back.
JK: If changing the plugs helps, i would look closely at the plugs that were removed. Make sure they all seem the same color. If one is oil fouled, or looks a little greenish or orange (depending on which coolant is in the system at this time) this would indicate an internal engine problem. If one is totally black, this would indicate a rich fuel condition which may be caused by a faulty injector or is more than one is black, then i would suspect a leaking fuel pressure regulator.

1991 Pontiac Trans Am GTA Engine size = 5.7 Repairs: Spark plugs, wires, cap, rotor, distributor, injectors, fuel pump. Question = i have a 1991 GTA it was running fine when i parked it a year ago i got it out and it was not running right, i replaced the fuel pump, performed a tune up, and replaced the distributer and then the injectors and still the problem exists. I have it down to cylinders 2 & 6 are missing. I have injector drive via a noid light and i have spark. Have tried different wires and spark plugs to rule that out. Also put in a second set of injectors to rule that out and ran a compression test and have about 170 PSI all the way around. Looking for more advice because I am running out of places to look.
Answer: First thing to do would take a fuel sample in a glass jar and check for contamination, or just plain old bad gas. Contaminants will separate from the gas after sitting a while. If spark is good, plugs and wires are good- make sure you have spark at each plug wire. If all is OK, i would suspect stuck lifters, or worn cam lobes. Worn camshaft lobes will not show up on compression test.
