My 1990 buick century custom starts but when you hit the brakes or try to put in gear shuts the car off why?
I just changed the spark plugs cause it was runnin
real bad found all 6 had broken porcelain, changed
wires, plugs, coil packs, new alternator. But now i
start it up its still running like crap at idle, revs
good, but stalls when i open the car door, or put my
foot on the brake, or try to put it in gear just shuts
right down with a check engine light and not
flashing any codes.
how is the fuel pressure? change the fuel filter and see if u get better idle. also rough idle can be from a miss fire. did u change the module under the coil packs?
