RX acting weird
Hey guy`s, a funny thing (started yesterday)on the highway heading home. I was going around 62-65mph and in my rear view mirror noticed a vehicle coming up on me rather quickly. So I punched it to get moving a little , I could feel something going on (like it wanted to go) but it didnt feel like it was going any faster. Okay, I thought to myself, that was odd. Then this morning pulling out on to the the two lane Hwy, it acted like it wasnt responding correctly to the throttle? I have drive by wire, so I dont know if some sensor is going bad, or if it`s the transmission or what? Right now it`s intermittent which can be bad (hard to diagnose) no codes yet either. I am really concerned this thing will act up when trying to pull out in traffic, you guy`s have any clue what could be going on here?

Check for any pending CEL's.
Try resetting the ECU, have it relearn your driving habits.
^same thing I posted on bitog
EDIT: did the rpms actually change when you pressed the accelerator down further?

To tell you the truth, I didnt look at the rpm`s. (yeah this is the same post from bitog) I figured why type it all over again? Hahaha.

But why would the 02 or the air fuel ratio sensor make it act like it was not responding? I cleared the ecm with my scanner. (there were no codes) just to see if it makes any difference. We`ll see what happens, I`m sure that if something is going out , I`ll know soon enough.

Another problem that could cause this is a loose throttle linkage bolt, under the cover, to the right of the manifold, I think. My SC400 had a loose linkage bolt and it made the car run like complete crap.
