No I haven't really messed with the truck it's not my current daily driver.. On another topic I have always used sea foam for cleaning gummed up fuels systems (Mainly Carburetor)with good success.. Is there a better additive to use for fuel injection systems?

I looked for chewed wires because I have rad of several cases of this happening...but will continue to look... I wondered about the injectors, this is what happened to the last motor, it sat and I bought some rebuilt injectors and one was defective and it filled my my cylinder with gas and hydrolocked the engine and I hit the key and snapped the rod into pieces. So I have been running some sea foam my gas hoping to clear them up

I have a 2001 2500HD 6.0 gas, it sat for a year or so. Now I have multiple miss fire code. I hooked up my scanner and it's Showing Cylinders 1,6,8 are missing firing. They appear to be working on idle. The plugs and wires were new when I parked it.. Any suggestions where to start with this ?

Thanks for the Reply I looked at another blazer 2 wheel Drive last night it was a 2000 year model and it looked to have a EGR valve sticking out of the front of the intake or something similar, do all the 2000 model years have the intake issue of leaking ? and is this the same engine I have now ? Thanks again

I currently have a 2003 Blazer with a 4,3 engine, and when I bought it I was told that it has a series 2 engine, How many different engines were there for these trucks, ? Can someone tell me the differnces of these engines ?

I have a 2001 2500HD With a 6.0 litre, Do not buy the Flowmaster Cat back kit they only last a year , I spent big bucks and a year later the pipes broke right out of the muffler I called and they didn't want to work with me and told me the kits were not built as heavy.. I since replaced it with a custom system with a "V Force" Muffler sounds good and not as loud as the flowmaster and it has 2 tailpipes.... When this goes bad i'm going with tailpipes only.....
