i took my truck to stealer today to have them look at injectors. there is a pinging noise when you are pulling from a stop. stealer told me that it was the belt slipping due to a weak tensioner. did not mention a thing about the noise. it almost sound liek a valve or like a gasser when octane is not high enough. any suggestions?

do you use an additive, if not try some(any) and see if it changes, that will tell if its pilot injection. my truck got quite after running some and i have run 2cycle/engine oil/power service with fuel. check out fuel discussion area for more info on this.

Mine had a fuel knock that sounded like a rod knock, the dealer replaced all 8 injectors and it went away totally and the engine is quieter at an idle.

When was the last time your fuel filter was changed? I started to get a loud tapping noise, especially during acceleration and @ 65-70 mph. I wound up changing the filter as it was due (15,000 miles). The tapping went away! They're very quiet now! A little more noticeable pep also. I cut the filter open and it was very dirty.

Your dealer doesn't have a clue.

i change my filter about every 7-8k. thought the dealer didnt have much of an idea escpeially when i called back to see if they could go ahead and check balance rates , after i asked them when i brought it in. service guy said the tech has never heard of the injectors being noisy. i also told them about a slight feul smell in the oil.
