2009 Vibe 1.8ltr.
Is there a relearn procedure for my TPS ? Seems like my cars Acceleration is acting odd. RPM drops quicky when taking your foot off the Accel pedal. When at highway crusing speed, takes a few seconds to kick down into a lower gear (gives me a rough shift). Took it in for a diagnostics on the trans, Trans was good, no codes on reader, shop says my TPS was only reading up to 80%. Is there a relearn I can try before I look for a new Throttle Body ? Thanks in Advance.
