Question about 1991 Geo Storm
The self diagnostic says code 44. The problem is intermeidiate, runs normal sometimes and then it will stall at idle. On the highway it will run normal and then all of a sudden the engine light comes on and the car boggs down, then it will suddenly go back to normal and the engine light will go out. This all started suddenly and without any warning. I have replaced the o2 sensor,air idle valve,cap and rotor. Vacum test is normal until the car tries to stall,always starts back up but doesn't always stay running,again intermitant.
Maybe try replaceing the ingnition modual. that part can do a lot of weird things to these cars. its located inside the distributor cap, really easy to do. about $40 and 10 mins or less. sometimes as they start to fail they do odd things sometimes but not always
