First of all, GREAT site Thank You.
Truck was stored for 4 years, ran fine previously with 56000 mi, started 3-4 times in yr. Fuel pump went bad and bad gas in tank. All fixed, after awhile p0300 , the only code,came on with a noticeable miss, worse cold. Runs good at speed and accel. Cyl # 4 fouls quickly. miss worse on even side, #1 with only a few. 3-5-7 quite a few. Cleaned MAP & throttle body.Compression 140psi. Checked wires, coils run @ 35-40kv, even though at 2500 rpm they all went down to about 10kv. It was an old scope and had to ck each cylinder individually. swapped coil #4 & #1 no change, exhaust pressure before cat on even side .65psi. Pulled injectors on even bank looking for leaky ones. All held pressure@ 75psi on bench test with good pattern. With EZ-scan tool 6000 A/F ratio 14.6. I have the scan tool results, if they could be of help and perhaps someone that is in the know may be able to come to an conclusion. Thanks Doug
The left front is the only issue. I replaced two bearings and a speed sensor. I used top quality parts. Front end is tight. all new ball joints, tie rods inner and outer as well as front brakes.
The front passenger side was worn more than the drivers side because the ABS fires on that side every time when stopping.

I recently replaced the alternator with a OEM reman unit. Disconnected negative battery terms before installing, reconnected after. Voltage output looks good but I am now getting service engine light. Had to remove/reinstall air intake from filter to manifold. Any ideas what might be causing the light or how to reset? no other info displayed.
changed radio and had problem starting it but finally primmed it enough and it did. the next am nothing. what could it be?
you can't read the speedometer on the dash not working and then the truck shout down and says reduce power you can pull over and wait few minutes the it will crack back up something is going on with my truck thanks penny
I just bought the truck and I am trying to find out if there is any help on this injector problem
Is this likely the module on the dash?
