Very recently I started having problems where my car has become harder to start (as if the choke is not working), and at times the engine runs rough at idle and sometimes stalls. Sometimes when stopped at a stoplight at idle, the engine will hiccup followed by a surge of approx 1000 rpm. I've had the car in twice, checked out in detail on the diagnostic tester, they replaced the thermo switch, evrything else checked ok. This has been an intermitent problem, so of course when I've had the car to the garage it was running fine at those times. As of yesterday the car will not start. The engine spins over fast but will not fire up. My mechanic said it could be my computer ??!! I'm wondering if anyone has had silmilar experience / symtoms to mine, and what was the fix / cost. Anyone have to replace the computer? If so, at what cost? Any information would be most appreciated.
