Below are pictures of the conversion from a dual throttle body Cross-Fire set up, to non-computer controlled carburetor. Why would I go from fuel injected to carb might you ask? Because when something goes wrong on a near 25 year old Cross-Fire set up that no one can work on, it's a royal pain in the....... yeah. You know! This particular design was GM's first attempt at making cars more fuel efficient. It met with limited success. Some love and swear by this set up, others use them for boat anchors. The Cross-Fire set up was plagued with problems, and was discontinued soon there after in favor of the Tuned Port Injection system. This Cross-Fire did well for 150,000 miles though before having problems. So, it served it's purpose.

The reason why I decided to go with this set up is simple. The car ran perfectly for about a year after I purchased it, and then shortly there after, it started having problems. The CHECK ENGINE light kept coming on, but wouldn't put out codes, and no one could fix it, because no one was familiar with this old of a set up. One day, I came out and started the car, and it immediately would idle at 2500 to 3000 RPM. I wasn't sure if it was the computer or a major vacuum leak. Either way, having a car that nobody could work on just didn't make any sense.  If the manifold had to come off and be reseated, providing the vacuum leak was there, it just made sense to get rid of it all, and put a new manifold and carb on and be done with it. Something that anyone could work on, and something that was the least expensive to do. Below are pictures of the three day long job.
And here we have a picture of the newly converted Carbureted set up. Complete with nice new chrome valve covers and Edelbrock breather. Very Nice Indeed!
