Question Asked: Engine Misfires
October 12, 2010, 04:59 PM
Problem with the 1990 Chevrolet Lumina Base 6 Cyl 3.1L (88,000 miles)
June 3, New spark Plugs installed. (Original Spark Plug wires remain) July 15, Power Brake Booster Replaced. Shop said battery was disconnected and computer needed to automatically reboot. But the engine stalled all day at stops and when coasting.
July 19, Shop ?cleaned? idle control valve and stalling problem stops. But the Engine now misfires.
August 9, Shop tests (and dislocates coolant reservoir, now rubber bushings are cracked/split) and decides #5 is misfire but they are not responsible. When the engine is cool, it runs steady but as engine heats up, misfire starts. Shop # 2 says New Spark Plug wires must be installed and Induction Service required.
Considering all the problems that GM created with the W-cars...AND these added factors: the serp belt is worn out, the motor mount bushing is split/cracked, the front windshield needs replacing...should I even consider keeping this car? But then why scrap a car with 88,000 miles that can get 32 mpg ?
