Bosh Iridium plugs in a "W" 4.3 Vortec
Hi Everyone,
I am posting to ask if anyone here has used the Bosch Iridium plugs in their 4.3 "W" engine. I have installed them and I seem to have hard starts and misfiring... I have put new wires and a new ACCEL Cap and Rotor, I have always used AC Delco plugs before, but it has been a while since I had done a tune up and it is misfiring the same way it was with the old parts... It is also worthy to mention that I have a Comp Cam 270RR and I have some light head work done and a cold air intake and the engine has only about 65,000 miles since I had it rebuilt... I am wondering if it is just best to go back to the AC Delco plugs. Any suggestions would be appreciated!!!
