When cruising down the highway my acceleration suddenly dies on me. Pressing the pedal to the floor does nothing for 5-10 seconds and suddenly I have acceleration back. It’s gotten to a point where it is dangerous to drive as I am just coasting along until it kicks back in.
This usually happens more in the summer than winter and is most noticeable when I am on a highway with rolling hills. My cruise control has no idea what to do when this happens and redlines the engine when it is able to get the throttle to respond. I sometimes notice the power cut too when I hit a bump hard or go around a sharp corner.
I’ve had a complete tuneup recently. New O2 sensor, MAF sensor, throttle body cleaning, air filter, spark plugs and it still goes haywire. I’ve even reset the system several times by leaving the battery off overnight and manually reset the TRAC system with no luck.
I’ve been all over the Internet trying to solve this issue for several years and so far it is just getting worse and worse. These fly-by-wire systems drive me nuts… Any ideas? Thanks.
