Hello all,
I bought a 01 Chevy S10 with 4.3l. It's has a P0300 code on it and I'm trying to find the problem. I've changed all the plugs, wires, distributor cap, rotor button, changed the crank sensor and it's help but still have the code and i get random service light flashing and that i know is bad. I'm thinking the spider injector may be the problem i'm seeing multiple misfires on cylinder 1 and 4 from the history. I was wondering if you could take a look at my data file and tell me what you think? Any help would be greatly appreciated. I am very new with HP tuners but loving the capabilities so far.
