Thread: 00 gtp shifting first into second

I cleaned the maf, cleaned it with maf cleaner. Seems more stable but problem still persists, Saturday and good tech friend of mine and myself are replacing the rear valve cover gasket and putting on sd headers so we will look into it more until the, I'm getting 11 mpg. Fml

For a car sitting that long, replace all the plugs and wires and definitely change the fluids for the engine and transmission. After the cleaning of the MAF sensor, did any other codes pop up? How about the TPS? You mentioned it in an earlier post. Do you have a scanner to look at data? Does your tech friend have a smoke machine to find any possible leaks? And at 11 mpg, I would say you still have some issues going on. As far as modding, I would wait until the car is running smoothly before doing that as it could compound your problem if the mods don't go as planned.
