Default Update on the Cobra

It's been a little slow in here so I decided to add some updates on some of the things I've been working on. The Cobra had been running pretty good after I got the final tune done. That was up until one day that I was heading out of town to visit a customer up north.

I decided to drive through a car wash on my way out. The place I go is a drive though wash and I was just exiting it when the car all of a sudden died and wouldn't start. As I was trying to figure out why I discovered that the MSD box had died. So I bypassed the box and ran the car off the coil. The car ran great the whole trip with the exception that It wouldn't rev past 4500 rpms or the boost would blow the spark out.

When I got home I ordered a new Mallory box to replace the MSD box. I ordered it from Summit and when it arrived I installed it. The car ran great after installing it. About a week later I had to go to another customers up north. The car ran great all the way up there and for the couple days I was there. I'd driven roughly 500 miles. On the way home I got stuck in traffic around San Jose. That was the first time The car had sat for more than a few minutes without going 40 mph or faster. Anyways after about 30 minutes the car died. Luckily I was on a side street so I pushed the car into a parking lot to look at it. Since that was the same issue I had with the old box I tried bypassing the box again and the car fired right up and I drove the rest of the 500 or so miles home without any issues.

I called Summit and got a replacement box which now works fine. However, I now ran into a new issue where at a light cruise after the car warms up I get a misfire. I tested the coil and the grounds thinking it may have something to do with them but they tested fine. I was so frustrated with it that I called Phil and asked if he would take a second look at it to see if maybe I missed something.

As we were looking at it he mentioned being able to smell raw fuel which I also noticed a while ago but hadn't looked into. Phil said that the misfire could be caused by the EVAP canister being full of fuel. So the following day I pulled the EVAP canister off (it's located in the front passenger fender) and sure enough, it was full of fuel. I poured the fuel into a gas can and the misfire is gone. I still need to buy a new EVAP canister as well as a new set of plugs but have to wait until I get paid again.
