Starts up like normal but jumps up to about 3 grand on the tach then falls down to 1.5 and stays there, engine surges at this idle. Runs good on the road till u have to stop and surges(jumps a little). Have checked vaccuum hoses and throttle cables, can't figure it out, took it to get coded and it came up P1294 and engine lite stays on most times, will go off runnin down the road and sometimes goes off when just idling. Please Help.

P1294 indicates a vacuum problem or a idle motor control problem. Since you already checked for vacuum leak then the iac on the side of the throttle body will need to be removed and cleaned. The best thing to do is remove the whole throttle body so it can be cleaned as well - both with carb cleaner. The idle solenoid (motor) on side of throttle body should be removed to do a through cleaning. All of the black needs to be removed from inside both before remounting to the intake. Make sure all connections and bolts are tight before starting engine.
