Timing chain 99 silverado
Does anyone know if there is a way to check the timing chain on a 99 or newer silverado, Im kinda on a last ditch guessing effor to fix my truck. One reason Im asking is I have backfiring along with if I give it alot of gas it lags in and out and will rev up to 5500 rpm before shifting to 2nd.

You may want to remove the distibutor and look closely at the teeth..
I have had a couple with the teeth worn causing what you are describing

Hey Bill
I had a hesitation problem as well, seems like its fixed know, what my mechanic did was clean the the throttle body throughly, put di-electric grease on the electric connectors of the fuel injectors , he said there was a bulletin on that chevy that said that some fuel injector problems where caused becase of corrosion. Also he put a new mass air flow sensor, it wasnt really bad but the reading it was giveing was not a stock specifications so just so everything could be like it once was, he replaced it. So far its been good, clean throttle response, didnt notice but throttle response before was a little rough compared to it know. Ive been hamerring it and still know hesitation, feel alot tighter though, at 60 mph when i floor it tugs. Anyways just to let you know my truck has 84,000 miles, 5.3 V8. Also i posted a a thread before that i though i fixed with cahing some spark plugs, apparantly that didnt work, but for know its good. Good luck, know its time to get out of here , laker game on soon............. Ruben

Fixed
I finally decided to take mine to a different chevy dealer in a different city. they had for 5-6 hours and found that my (Mass Air Flow Sensor) was very dirty! but they only charged me $82, I am very impressed and would recommend them since the dealer in my city told me over $1000 to fix it. Im totally happy for what I paid for- I can burnout again but not like it did when I first got it but Im happy, it doesnt backfire or hesitate at all.
