Re: 97 Chevy s10 miss under load

P1336 "Crankshaft position system variation not learned" must be performed with a bi-directional scan tool. The run of the mill scan tool is not capable of performing the relearn on the 2.2L engine. I can email you the procedure if you need it, but most shops will have it.
