Hey guys, I have a 1993 del sol S with a swapped jdm B16. I have been having bad luck with this thing since the swaps done this summer. The synchros died on reverse and 5th so I had to get the thing rebuilt and that cost a ton. When I got my car back from the guy who did the swap he said the Idle Air Control Sensor was missing and he put a "blank plug" in so the car would start( but the shop that did the transmission said the IACV was there and did not know of any sensor for the IACV)?, also that a plug near the TPS and throttle body was cracked. Now for the problems, the revs jump at 1500rpms to 1600rpms, which sucks if your driving and you hit that area in the rev range, it shakes the **** outta my car. Also whenever I hit the gas or let off the gas the car violently shakes, and sometimes the pedal would seem somewhat stuck when Id get into the car in the mornings at first. I know the throttle cable from my old motor was used, and the spring that its connected to was from the new motor, and the spring seems very stiff at times. Does anyone have a clue as to what would be causing these problems? Any advice would be greatly appreciated.

 

Anyone, please.

 

the revs jumping sounds like a vacuum leak, and as far as the throttle cable sticking, spray some wd-40 or some other penetrating spray on the throttle cable and work it back and forth.That should help lubricate it and loosen it up. As far as the IACV, I have no idea without seeing the motor.

 

Thank you very much.
