Hopefully, a cure for my intermittent problems...

1994 900 SE turbo
130,000 kms (80,000 mi)
New DI, less than 1 year, 40,000 kms
Have been having these intermittent problems with the engine hesitating on occasion, normally after at least a 100 km drive, then it would sometimes jerk in bumper-to bumper traffic. It got worse last week, jerking even at 3000 rpm in normal highway driving. But no CELs. Sometimes a smell of fuel as well.
Cleaned the TB, IAC, spark plugs, etc but it would always come back after a long drive. All hoses intact.
When I got it to the dealer, it sat for a long time with nothing going wrong, went for a 20 mile test drive with the TechII connected, and still no fault codes. The chief tech there suspected one of three sensors -
MAP sensor, the IAT sensor or another temperature sensor on the cooling system. He said if there was an intermittent fault that made the engine run slightly rich, I would feel a loss of power, and there would be no CELs if it was any one of the three.
The MAP sensor has now been changed, and what a difference! No more stalling, more torque at lower rpms, wow! I did a quick 150 mile drive to check it out, and the difference is almost like night and day.
Just to share the experience. :o)
