Question about 1994 Chevrolet K1500
I recently replaced the engine and everything north of the transmission. I didn't replace or rebuild the TBI or the fuel pump. The timing was set professionally by the specs. Once we did that it developed this surge at idle. It will bounce between 600 and 800 rpm until it warms up. My sense is that it has to do with fuel metering. What do you think it is?
Have you tried cleaning the IAC motor on the throttle body this controls idle
