1990 L98 Tech 1A Scan Data assitance
Hi:
I am having a problem with the idle on my 1990 L98 with automatic. Idles fine in Park but when in DRIVE at a stop light the engine idles rough (starts to chug, shake, seems to want to stall). I have scanned the car with my Tech1A scanner. No codes present. As I was going through SCAN Data and comparing it to the FSM Section 6E3-a-12 5.7L (VIN 8) Driveability and Emissions I came across the information below. I am not sure what this means or how to interpolate it. Any help would be greatly appreciated.
Scan Position Units/Displayed Typical Data Values
MAP KPa/Volts 30-70/1.02-1.50(Varies with Altitude)
My scan gave me 1.5-1.65
Scan Position Units/Displayed Typical Data Values
Block Learn Cell Cell Number 0 or 1(depends on Air Flow % RPM)
My scan gave me 4 Cell
Scan Position Units/Displayed Typical Data Values
Blk Learn Enable No/Yes No
My Scan gave me Yes
