I agree with your plan & also recommend you have someone work the gas pedal while you watch the T/B fully open & close just to be sure it's adjusted properly.  |
Thank you for the reply!
It's an early Boxster '97 2.5L engine, no e-gas, around 70K milage. I'm pretty sure the T/B is fine, when I was cleaning it the cable was long enough to allow TB to be closed completely. Plus I did not have the issue before ever and I don't think the cable would "shorten" suddenly. Another observation, when I'm driving downhill and letting the engine to decelerate the car by letting off the gas pedal, this problem can occur randomly. I.e. I would feel that the can decelerates and accelerates while I'm not touching the pedal e.g. not touching T/B.
The problem only occurs when the car is in motion, idle RPMs are stable and no problems whatsoever. Seems like the higher speed - the higher probability of RPM to get stuck.
