Ok heres the deal. My cars been running like crap. WIll it run with a bad ecm. And not set any codes. I can unplug sensors and it doesn't change anything.

 

Does it throw a code when you disconnect any of the sensors? mine set a 21 when I unplugged the TPS. and are you sure the SES light bulb isn't blown?

 

Accel cap and rotor made mine run like crap till I changed it out for A/C Delco cap and rotor

 

Unplug the MAF, thats one sure fire wall (and easy) to get it into limp.

 

occasionaly while driveing the ses light comes on but it will go back off. When i stop and check it i get no codes. I've unplugg every sensor one by one and it changes nothing. Hell i even took the tps off.

 

Codes do not clear themselves. If the SES light comes on while driving, it's still in there. Will only delete when power is removed for a few minutes or reset by code scanner. Check your code reader. Will flash 12 then all codes in memory then 12 again.

 

I second that about accel cap and rotors. They flat out suck. The rotor is too tall and the top of it chews up the distributor cap. Gets this fine plastic dust/shavings all over the place and on the terminals under the cap. And i didn't get a "bad" kit because i'm far from the only one who has discovered this problem..........
