TPS enhancement question
I performed the throttle position enhancement as outlined in the site linked from TechInfo. I set my multimeter to measure resistance in the range of 20K ohms, connected the black wire to the ground (bottom prong as TP sits in TB), and connected the red wire to the sender (middle prong as TP sits in TB).
This is where it gets tricky...at idle, the multimeter read 1.03. At WOT, the multimeter read 4.78. I moved the TP sensor around (and even bent the tab inside to give a bigger adjustment) to get the multimeter to read the specified 0.70 at idle and 4.2 at WOT. After this, I drove my car and the shifting was so much smoother and the car ran great, however, the check engine light was on.
When I came back, I adjusted back nearly to the way it was. I have it set so the multimeter reads 0.95 at idle, 4.63 at WOT. The check engine light is off and the car still runs fine.
Does anyone have any idea what the cause for this is? Did I do something wrong? I wouldn't think my '98 would call for any difference than the model year of the car that the instructions came from.
