Random Elec Problem Gremlin 1994 3100
 

1994 Cutlass Ciera S, 3100 V6......While driving after about 45 Mins Airbag light Starts flashing, Anti-Lock Lock light comes on, CEL comes on and off, charge light flickers, ac shuts off and car temp goes up, car bucks uphill until it downshifted, Car will come out of OD and will not go back into it, Happened every day...Then replaced, ECM, ALT and battery, spark plugs and wires..., After I replaced the battery the bucking uphill went away and has not come back and all the problems stopped for about 3 week and randomly did it again last night except it's just the airbag light and antilock and CEL, No going out of OD.....If I pull over shut it off and turn it back on the problem goes away. My question is could this be related to an ignition switch problem? Anyone know of any common issues this sounds like?? Its a gremlin for sure...But happens so much less often now after the parts I replaced its not a HUGE issue but there is still something...Just figured I would ask to see if anyone may have something on this, Thanks Guys
