Surging 02 S10 02 lq4/4l60e. Tune consisted of stock with the removal of Rear 02's and VATS. The only mod I have done is a l92 intake and holley 90mm throttle body.
I fired it off last night and with lots of effort it finally fired up. I have found that cylinders 1 and 4 are missing. I have checked my wiring and all is fine. I have tried swapping coils and those are fine. Next I plan on changing injectors out to see if the problem moves. Another problem I am having is I can not rev the motor up at all. As soon as I touch the throttle it just wants to die. After a few atempts it starts to surge real bad like the O2 sensors are bad. The only thing is they are brand new Delco's.
Cliff notes. 6.0 swapped into s10.
Need ideas of why truck surges and will not rev up.
