    4v Coil Packs

    Rickyll7 I couldn't agree with you more... about not listening to what these guys write in magazines and to sell parts in catalogs... thats why I hit up this site to get a second opinion. The mags and catalogs always tell you what you want to hear... not what is best for your car. I've also...

    4v Coil Packs

    According to the catalog it increases voltage to 60000 volts, up from 20000. Would that make for a longer hotter spark making a more complete burn? What are you running for an ignition system? I hear you on the Tune and Tires... I had it dyno tuned and bought a set of Mickey Thompson D/R...

    4v Coil Packs

    I'm thinking about adding GMS 4V Pro-Series Coil Packs to my 04 Mach 1. Has anyone done this mod and what were your results? I saw a magazine write up for a stock 05 GT where they gained 30HP. Having a tough time believing that one... but if its real I'm in. My Mach has the following mods...

    04 Mach 1 Power Loss

    Thanks again for all your help Guys! Checked the oil... no smell of gas. The sound does appear to be coming from the EGR, weird that I never noticed this before. Got a bit frustrated over the weekend and took the car for a drive. Like the say in the military I was driving 'for effect' ie gave...

    ticking....

    I was looking for a tick just this past week on my car. My old man showed me a nice trick. Use a standard screw driver with a long shaft (18-24 inches) with the metal end on the component and the handle tight to your ear. It really amplifies the sound. Keep moving it around on different parts...

    Mach 1 Stock Exhaust

    Thanks for the help guys! I have a non-stamped X-Pipe on my car that was installed before I bought it. It has a healthy layer of surface rust and I couldn't tell if it was stock or just a cheap after market mid-pipe.

    04 Mach 1 Power Loss

    Thanks again guys for your posts! I removed the MAF Sensor and cleaned it using CRC MAF Cleaner, let it set for about 10-15 minutes to be sure it was dry before I reinstalled it. While I was waiting I climbed under the car and shook the mid-pipe as best I could. Then tapped it with a small...

    04 Mach 1 Power Loss

    Thanks for all the ideas guys! I'm going to try cleaning the MAF Sensor today after work and possibly replace the Fuel Filter also if I have time. I'll post my results afterwards. I have a question about checking the Cat... How do I know if its bad? Also... the mid-pipe looks to be cast iron...
