Hmmmm.. Last year my nephew had a HHR and the cat went out. Well like an idiot, he let the exhaust shop talk him into a new cat, mind you the car was 6 yrs old and 70k miles at the time fully under warranty, the shop put a non CA cat on and backwards at that. Couldn’t pass smog and I couldn’t find a place other than the dealer to buy another one that was legal.. I’ll look at the “got exhaust “ Thanks
So I’ve got about 95k mikes now and was wondering if I should change the plugs and wires? Runs fine, gas mileage is shit. I get 15 ish on the freeway, LA to SFO on I5, for example and every now and then at idle in a drive through I’ll feel a little roughness. Guess it could be the A/C compressor then then again the A/C isn’t on that much to account for it. So im thinking, over 90k it’s probably a good time to change the plugs and wires. Looks like th AC plugs are the best choice? Although I don’t know where to source them from. Any other tune tune up ideas? I’ve ran few tanks with the Lucas Oil fuel injector cleaner. Hasn’t made any difference. Brings another idea. Injectors. Are they a bitch to change? Necessary consideration? Truck is a 2008 GMC 1500 5.3L non flex fuel 2WD. Thanks
08 GMC replied to 08 GMC's topic in Gen III and IV Small Block & DrivetrainThanks, how do I measure the rear end to identify which of the three different sized rear ends there are? Trying to to get a gasket for the cover and I don’t know what size rear end is in the truck. 2WD, 1500
I have a 2008' GMC Sierra 1500 2WD with a 5.3L non flex fuel. My dash shows a light lit for the tire pressure and when I check the pressures they are fine but the truck says I have like 2 psi in one and normal in the others. Is it common to have to change the sensors? Thanks

08 GMC replied to 08 GMC's topic in Gen III and IV Small Block & DrivetrainThanks, this made it easy... No need to worry about it I guess
08 GMC posted a topic in Gen III and IV Small Block & DrivetrainI cannot seem to be able to find where the fuel filter is nor where I can purchase a replacement fuel filter for my 2008 GMC Sierra 1500 5.3L (non flex fuel) truck. In my previous trucks it was easy to find and replace as it was inline from the fuel tank to the engine but I cannot find it in this truck and when I search for a new filter on line nothing shows for this truck mode. Thanks..
08 GMC posted a topic in Gen III and IV Small Block & DrivetrainSo, I have a 2008 GMC Sierra, 5.3L (non flex fuel) and I want to change the oil in the rear end. The internet list two different rear end diff's sizes and I do not know how to determine which rear end size is in my truck so that I can determine the correct amount of oil volume that should be used. Guess I could add until it's below the plug, that that's assuming I purchase the correct amount as if I'm short I'll have no means to drive and get more. Thanks
