surging while idling and driving
surging while idling and driving guys have a 01 ls1, asa motor, runs in closed loop as its a race motor, no o2s.anyway its been sitting for a few weeks and its in a 69 camaro, so we cleaned up the wiring, installed alot of relays etc to make the system neat and orderly. i just drove it and it ran fine when cold, then once it got up to 160, it surged going down the road at speed and while idling. has a coolant sensor code, but it ohm'd out at 200-220 at 180 which is about right.
what else might it be? it has an atl fuel cell with 2 pumps, both pumps act the same. do no have fuel pressure gauge, but can borrow one.with that said i am leaning towards temp sender for the pcm, and or plug wires, but i am not up on my fuel injection tech\
any help woul dbe great
