I have the 4.6L v8 engine. 106,000 miles
ODB2 question.
ok so over this last year i have managed to shoot 3 spark plugs...and have had all instances repaired...but the last time i shot a spark plug my ODB2 system didnt thorw a single code(i checked using two devices)..i am currently having some small issues with my truck(mainly a rough idle) and im having a hard time getting it ironed out...if i had a code to go by things would go easier...is there anyway for the ODB2 system to fail? Could a fuse have blown? Is the system not as effective as i thought?
Rough idle question.
as i have already stated, My engine is having a rough idle in N and gear...it will be doing fine and all of a sudden the RPM drops and and the truck shutters...then the engien idles ok for about 10 seconds, and then repeats the cycle. When in Nutral the engine apears to idle rough from idle all the way to 2200 rpm. I have checked for kinked air hoses and found none. The first two of my spark plug blow outs were repaired via helica coil...the latest was done with this kit that uses a longer heavy duty plug(that isnt gaped like my others, bosch 4 pin platinum) and also had to replace the High voltage piece between the coil and the plug(my other 7 have a braded wire, the one in question uses the standard Spring like piece)..so i have 7 bosch 4 pin platinum plugs with 60,000 volt coils...and 1 extra long heavy duty plug that is missing the high voltage connector that the other 7 are...I also have not replaced my IAC as i have yet to get an ODB2 code, nore have i cleaned my MAF...i run a fuel system cleaner twice a year...
any one else have any thing like this?
