I finally fixed the problem today fordaspire/WOOT.gif

When i finally figured out that the tps wasn't faulty by voltage checking, I reckoned the throttle stop probably wasn't adjusted right. Before i got this car somebody else might have tinkered with the idle setting to compensate for the low idle due to all the accumulated gunk in the throttle body especially on the throttle plate.

Since the tps is of the non-adjustable type I adjusted the throttle stop and set it just at about 0.58 V at idle and 4.3 V at wot. The resistance of the tps at idle is 1.03 k-ohm and 2.337 k at wot. I got the idle at less than 1k but decided to set it just a wee bit higher.

Keeping my fingers crossed I started the car and voila! No more rough idle! fordaspire/chili.gif

The idle was a little bit high at 1100 rpm so after reaching operating temp I turned off the car. I turned it on again and removed the IACV connector. The idle dropped and I adjusted the idle screw little by little to about 800 rpm then I reconnected the IACV. The IACV readjusted after a few moments and idled to about 1000 rpm. I wanted it to idle at around 800-900 but the idle screw was almost maxed so I left it at that.

I travelled short distances to test it and so far so good although the bucking when shifting to 2nd gear is still there.

Thanks to everybody who helped! fordaspire/icon_horns2.gif
