Hey Guys,

I just installed an OMNI TPS sensor because I was having some throttle/shifting issues. They have been resolved with the installation, but I have a problem with the idle bouncing now and it is really high when put into "park."

Here is what I did...

-Installed the new one to 4.51V at WOT and .48V at Idle (which should be about dead on)
-Cleared the ECU

I had to adjust the idle screw to get the .48V at idle from the TPS, stock was .35V, but when I had it setup for that and drove it around it wanted to die out. It idled at about 300. So with my adjustment the Idle is now about 800.

What do you guys think I should do since something is off. The Idle now bounces in "park" but at a stop light runs about 800rpm.

Adjust the idle screw and see if idling lower will fix it or adjust the Idle Air screw and see if that fixes some sort of vacuum leak that causing the idle bounce?

Thanks You

 

Well it looks to be caused from a vacuum leak at the hose when I put the seafoam in. I must have moved it enough when calibrating the TPS to make a small vacuum leak.
