Truck issues?

[dewandgin]

a miss under load could be fuel related or it could be secondary ignition related or maybe the code is for a knock sensor that is retarding the timing too far. pull the blink code and see what you have before we start throwing money at it

From the Wetside. like the darkside only Wetter!

Those injectors are very trouble free, aren't they, dewandgin?

Yea I think I have replaced one maybe two in 22yrs of working in a Chevy shop. It only runs 12-15psi so fuel pumps very rarely go bad

His problem sounds familiar but I hate throwing money at a problem. I would rather spend two hrs diag a problem and fix it with a single part then load the parts cannon up and start firing away.

its really easy to do yourself ya just need a paperclip

used to do this on all my old chevy's then call my chevy mechanic friend and get his input. Then watch my ex throw all sorts of money at stupid stuff anyway   I know use a mechanic and he tells me if I can go home and do it myself like my shocks

I tried the trouble instructions and got almost every code in my Haynes manual. Then started with the basics plugs, rotor, rotor cap and new wires. I found one culprit right off the bat the coil wire was shorting out on the air cleaner the next was a loose rotor cap. I replaced the plugs/wires/cap/rotor as well as the fuel filter. On a short run it appeared to work just fine.

Campmeat, my wife id looking into dipping into her 401K to get me a new truck and the daughter a newer car.

Thanks everyone

I have a 98 K1500,  autozone does it for free.  They will not reset the OBD but will give the codes and print out solution for you.

your 98 is OBDII his 94 is OBDI totally different diag scanners used to pull codes most auto parts store only carry OBDII scanners witch is basically 96 and newer rigs!!     id use the paper clip and jump the ALDL connetor and cycle the ignition and count the flashes of the engine light to pull codes then can cross that on line for fault code!!

Day 1
I tried the trouble code  instructions and used a jumper on the ALDL and got almost every code in my Haynes manual. Then started with the basics plugs, rotor, rotor cap and new wires. I found one culprit right off the bat the coil wire was shorting out on the air cleaner the next was a loose rotor cap. I replaced the plugs/wires/cap/rotor as well as the fuel filter. On a short run it appeared to work just fine.
Day 2
I did a freeway run with hills today and not one issue after I replaced all the wires plugs etc. And I got gas at a Union 76 for $2.79  . The main issue was the coil wire was shorting on the air cleaner and the rotor cap was not seated allowing it to move up and down. The rotor even wore a groove into the cap that was close to 1/8" deep.

Be sure to clear all your codes. But before you do write all your codes down and then clear them. That way the next time you have a problem and you have a code you will only have a newer code not an older one that may or may not be current.
