I have a 2000 chevy s10 4.3 the injectors went on it and I replaced them with the conversion kit also replace the cap and rotor, vehicle now starts and ran, however it now misfires on mostly 3 and 4, it will start and idle fine and at first it runs normal even under higher rpm, however after a short bit it will start to misfire. the only codes i have is random misfire. does anyone have an ideas aboutwhereto go with this?

 

Did you replace the plugs and wires along with the cap?

 

the truck went stop running going down the road like no fuel, the fix was the injectors, i just did that while i was at it, it was not a problem befor do you think the wires and plugs would really have an issue even though they were fine befor

 

If you put a new rotor and cap on I would repalce the plugs and wires. Then everything will be new.

 

and then the problem may go away for a while, but when it returns let me know how you get it fixed. I've been dealing with a 98 blazer for 2yrs, few thousand dollars, and mechanics that have changed everything except fuel pressure reg. and pump so far. I can't wait till someone figures this out.
