Well to start things off I have a 2000 Chevy Silverado pretty much stock except the flowmaster.I have recently noticed a problem well after my truck runs a while it starts to stall or miss, I can shut it off for a few minutes and the truck runs fine for a while, the local autoparts store put a code reader on it and pulled a o2 code so I replaced all the o2 sensors and the converters and still no change its driving me crazy so if anyone has had this problem please help.
Thanks

 

Intake leak?
Plug wires/plugs?
start eliminating things one at a time.

 

start with the cheaper ones and work your way from them

 

well the plugs and wire are less than 72 hours old they are the bosch iridium plugs

 

did it start when you did the plugs or was it already a problem?

 

I haven't had much luck with Bosch but I'm sure others have. The A/C Delco Iridiums are pretty damn good plugs and they are GM. You need to try to find a way to scan your truck and log the data so you can see what's happening. I agree, process of elimination is the way to go.

 

actually now that you mention it I believe it did start when i changed the plugs,wires

 

The old bosch platinums cause bad problems on certain vehicles but the iradiums are good plugs from what I know of. Plugs have to have been known to be bad brand new, particualarly GM platinums which I believe are made by bosch. It has been a few years since i've heard of a bad one. Try putting the stock wires back on it (easy task) and see if it goes away. Then plugs if the problem still exists.

I'm local and actually work in the Athens area. Let me know if I can help you out. I do custom tuning as well.

 

well i took it to the dealership come to find out it was my air filter cone style k&n to be exact it's the way it was sitting was causing the air flow to be restricted and the computer would compensate with more fuel causing the plugs to foul out. I wish I had thought about that before putting o2 sensors and 2 sets of plugs lol
Thanks for the offer turbogibbs I will keep you in mind
if something else goes wrong

 

That comes to mind that K&N or oil filled filters are known to mess with MAF sensor due to the oil coating on the sensor. All it requires is spraying some Electronic parts cleaner of MAF sensor cleaner on the elements to solve the problem. I've had this happen twice personally.
