Question about 2002 Ford Thunderbird

1 Answer

Curb idle on 2002 Thunderbird wanders between 850-1000 rpm

In drive rpm about 750-850 rpm. All readings are from cars stock tach. Tends to hold the high rpm during coast down, surges then drops suddenly after stopping then fluctuates at idle. PCM was reprogrammed about 6 months ago which did improve the condition. Symptoms have returned although to a lesser degree

I just bought a sunpro super tach2 and it shows that it is running to fast. whats the problem


There should be 2 adjustments on the back. A switch for 4-6-8 cyl use and a slider to fine tune the rpm. If you know your car idles at 750rpm, move the slider until the tach reads 750. The switch for cylinder numbers should be self-explanatory and must be set first.

How do i set the timeing


There is NO manual timing adjustment for the ignition. It is controlled by the knock sensor and the computer. If you need the timing marks for the timing belt, please respond and I will send it to you. If not, what kind kinds of problems are you experiencing?

RPM is over 400 rpm higher than it should be with no gas pedal.


Could be several things.. I would suggest replace the neutral safety switch, all O2 sensors and fuel and air filters, PVC valve and if needed plugs n wires..
The issue could also be a bad throttle body.. Should be a good idea to get it hooked up to a diagnostic machine - get the codes and then you will know more of what you are dealing with..

Have a great day !!

Need adjustments for 88 model carter 2 barrel carburator. fits 4.2 jeep


To set carb adjustment, first set timing correctly, then put both a vacuum gauge and tach on the engine. adjust one idle screw to highest vacuum reading and highest tach reading, then do the other one. go back to the first and re-adjust again, then the other. I find that if you have a mechanical screw or a solenoid that holds idle speed on the linkage, turn them back so that engine is idling at the lowest possible rpm without stalling before making adjustments, then when finished, bring idle rpm up to recommended rpm using those. On an older carb, usually the idle screw covers have already been removed. If not, you need to remove them before you begin, usually best done with carb on a bench.
