Dodge 12V Cummins Throttle Cable Replacement

Throttle cable failure has been common on 1994 – 1998 12 valve diesel engines, usually after about 30,000 miles on the cable. I am now on my third cable, and am curious to see if the new design will be more reliable. Twice I have managed to replace my cable in the nick of time […]

How to adjust the idle speed on a Dodge Diesel

How do I adjust the idle speed on my Ram diesel? The idle speed seems too high. First, trace the accelerator linkage to the connection on the fuel pump. With the ENGINE OFF have someone floor the accelerator and watch the fuel arm move. The best position I can describe is that it is under […]

Hunting For Horsepower by Alligator Performance

It was a busy Saturday. Trucks were lined up in the vacant lots behind Alligator Performance waiting to get dyno’d. This was Alligator Performance’s first event – and for a small, relatively new company, this was a big event. Alligator Diesel Performance opened their doors in Las Vegas in 2005. In 2009, they moved to […]

Nonetheless, when I looked the throttle body spacer over, I took up the challenge to install the unit myself. This isn't a hard one. […]

A Recommendation for Trailer Pullers

7.3L Powerstroke Custom Fuel System

Bigger injectors require more fuel. Lots more fuel than what the oem system can put out. And the oem stuff has many faults, which just makes it that much more appealing to replace the whole darn system! I was planning on doing some work to the truck and I knew it would be laid up […]

Cleaning Stickum Left From Vinyl

Just after the winter began winding down and the weather was beginning to warm up, I removed a large 30″ x 18″ vinyl sticker from the tailgate of my truck. No matter how much heat was applied, the back of the sticker refused to come loose. I tried everything, Goof-Off®, fingernail polish remover, paint thinner, […]
