i put the performance tune back on my 97` 4.6 f150 the 3 days ago and the computer is still making it idle funny, but only whenits in drive.. ive driven prolly 200 miles and even let it idle for 20-30 min and it still idles HORRIBLY. any suggestions. when im rollin down the road theres no problem but when i stop the RPMs drop WAY down, and if i turn the wheels the truck dies on me. its done this everytimeive changed the program on it but it usualy only last a day at most.
