I just finished rebuilding my 94 formula lt1 and now I believe I am having computer trouble. The car starts and runs fine but it will not shift into a higher gear than first. I did research and I guess this is called limp home mode. The car on functions to minium capabilities to get you back home. I'm going to assume it's not a transmission problem because the trans was just rebuilt. my next thought was maybe one of the sensors are bad so I replaced all of them (02 sensor, maf sensor, and such), still no luck. Also when I plug the maf sensor in the car dies right away so I dont understand whats going on there either. The engine was just rebuilt and we told them to build it just enough so we dont have to swap out the chip. They street ported the heads and put in a bigger cam (266in 276exh with a 110 centerline). they also slapped an msd ignition on it as well. I called msd and they said the ignition works on the stock chip so that narrows it down further. Im retarded with computer cars, this post is for my dad. So does anyone have any ideas here? Also im not sure if the cars showing any codes either, I just thought of checking that now.
