i have a 2001 Lightning and i just had it Smog Tested yesterday. i drove all morning today and after two hours at a friend's i was driving home and the truck felt fine, but, i stepped on the gas the SC went on for a few seconds and then it started stuttering. as long as the SC does not go on, the truck feels fine. what can it be?

 

time for a plug change at the very least

 

so, the plan is:
1) new fuel filter
2) clean MAF
3) check vacuum lines
4) maybe new plugs
5) what else?

 

5) pay attention to your thread on Lightning Rodder

 

i checked the I/C reservoir and i did not see the coolant moving at all. i waited a few minutes and nothing. then, i tapped the pump the coolant starting moving very slowly, you could barely tell it was circulating. now, i have a a couple of questions:
1) now that the pump in barely working, should i be able to go WOT without issues?
2) or does the pump need to be working correctly for the computer not to adjust the timing, thus causing it to stall?

thank you for any feedback.
