Welcome to the forum. You might want to try cleaning or replacing the IAC (Idle Air Controller). It comes apart for cleaning or just replace it. That has a lot to do with your idle and how the dropping of the revs.
![]() The other sensor is the TPS (Throttle Position Sensor) which can't be cleaned, only replaced. Both sensors are by the Throttle Body. ![]() The other thing: In the first picture are two wires running across the top of the engine. One is the Cruise Control, the other is the Throttle Cable. Make sure both wires are (sort-of) tight (not too much slack) and that the wheel that they are attached to is working freely. Last edited by CREWZIN; 14 Jul 2014 at 07:35 am. |

Thank you for the prompt reply, I did remove and clean the Idle Air Controller but to no avail along with map sensor so I'll replace it and the TP sensor and see how we go.
Edit. It doesnt look like i have a cruise control as i only have the 1 wire .. Thanks Again Last edited by ProperTricky; 14 Jul 2014 at 08:14 am. |

do not replace the TPS sensor, check it with a multimeter first.

with the car off but key in the run position, it should be 0.6v at idle, 4.5v when fully open. measure from the orange wire to the black wire
also, make sure you have the AC off while you're troubleshooting your idle issue. Last edited by rob342; 14 Jul 2014 at 09:04 am. |

Still waiting for my Dad to bring his Multimeter which hopefully will be tomorrow.
Something else worth mentioning is that there's a savage or hard hesitation/jerk when sometimes accelerating. But anyway thanks for the help I'll report back tomorrow |

Some cable lubricant on the throttle cable? Can't hurt.
![]() Is aircon on? A/C keeps idle high, and remember that defog (defrost) brings on A/C also.
