high idle and chugging

When you adjusted the timing did you short the diagnostic plug under your hood? If not, this could cause all these problems. You have to do it like the book says or you won't get it right.

thanks elton i dont think so is there a way to check, i am still leaning towards the tps from what i have read about is when you reinstall another one you can not just screw it in you need a ohm meter and feeler gauges please elton or anyone else correct me if i am wrong thank you.

yes, you need to properly adjust the tps TPS Adjustment Instructions
You should also make sure the codes are cleared and then see if any come back

thanks mma alex,how do i clear the codes? i just adjusted the tps with feeler gauges and no ohm meter dont have one but i am not sure why one is needed if you are just setting a gap.as soon as i started the engine the idle stays at 1200 rpm then press the gas and same old symptons hesitation 1500 to1800 rpms then back again i am sure it is something simple, any ideas

you're not setting the gap, youre setting the position of a resistive strip in the tps, against the throttle body. It needs to be angled correctly so the computer realizes how much throttle is being applied. Go out and buy a cheap multi meter. Its a good tool to have, and you can get halfway decent ones for less than $20.
As for the codes, unplug the ground wire from the battery, and let it sit a few minutes before reconnecting. I believe that should clear everything.

thanks elton for code clearing,well i just cleared the codes and i am still getting 7 flashes which indicate a tps but i have messed around with it enough the only thing i did not do was use a ohm meter has this happened to anybody like maybe their friends second cousins neighbours aunts brothers girlfriends uncle thank you.

Yep, this happened to me. I went into it just like you did, chasing problems the wrong way. It sounds to me like you need to go get a multi meter and the feeler gauges and adjust the tps properly. The old cap and wires and tps are probably in perfect shape, just needed to adjust the tps. It is very finicky to get just right, mine would only give a problem while the engine was warming up, at temp it worked great and everything was fine. when it was cold it would idle @ 1800 and surge real bad. I found out the hard way that the previous owner had adjusted it wrong after I replaced the cap & button, wires, plugs, coil, tps, coolant temp sensor(both), pickup coil, and a few other things I can't think of right now. Good luck. As far as the meter goes i have really enjoyed the actron meter I got for christmas. I got the one with the tach and dwell meter, it runs @ $49.99 I think.
