Finally after paying off and working on this car since sometime around october, i can drive my car, i got the plates saterday and have 7 days exempt for my inspection.Since i started really driving it the dic soemtimes says service vehicle soon, and service ride control but the both can go away and come back. The only code that is still current is p030 (isc rpm out of range) but there are a few history codes. I didnt write them down but i will update with them later. Sometimes while driving down the street the car will kind of jerk when accelerating from a stop it feels almost like tranny slipping but im not sure. it will do it until i either get on it ot put it in neutral and rev the motor a little then it goes away.Also what is the "range" for in the fuel data center mine always either says lo or 44....so i ahve no idea what that is. My mileage is pretty bad but getting back up there i guess its from the car sitting. When i forst started driving saterday i was getting like 4.6 mpg average!!! now after driving all weekend its up to about 9.1. Any help with theses questiong is greatly appreciated. I also want to say thankyou to everyone that helped me with previous problems and questions,...the caddy would still be sitting if it wasnt for your help.
