1992 Buick Regal QuestionsMy 92 Buick misses somtimes than seems to go away. but now its getting worse .Id like to know if the most likely reason is one of the 3 ignition coils, Plugs,wires, Vacum (1 answer)
58000 on motor One of the ignition coils has been changed That I can see dont see any vac leaks plug wires dont look old
Fitting broke right below hex and is flush with manifold. Inside dia. of plastic is "mushy" outside dia. is still very rigid and stuck in threads. 1"-14 UNS thread
