Much appreciative for all the help recently. Was able to pinpoint and correct a TPS issue. It was the plug. Found a throttle body with attached tps and wiring bundle. Took it all, replaced the old, worked with it a bit until the brain figured it out that a new one was in place, and away it went! Beauty. Thanks again.

what was the actual problem if you dont mind me asking? i have a problem that i think may also be tps related, however i've swapped a couple already and it does not seem to be helping. i have hesitation on accel.

It turned out that the plug for the tps was shot. The female parts (4 prongs) were so corroded and weak, plus the small wire holder for the plug was missing, that the connections could not be maintained. For a while we could wiggle the plug while the car was running and cause the motor to rise and drop in rpm's. Finally it just would not start, and that was when I got lucky and found the newly arrived Loyale in the wrecking yard to get the whole throttle body and wiring loom.

hmmm good to know. I know my plug has a corner missing as well as that metal circlip that helps hold it down. isnt that part of a main wiring harness though? PITA to change?

Cleaning up connections like that can be real hard,sometimes a commercial electrical cleaner spray will work often not.

What I use for cleaning very dirty corrosion of electrical components is a Pasche air eraser,this is like a small sand blaster used for fixing painting mistakes by abrading away the mistake.It just happens to work perfectly for cleaning off corrosion on electrical connections especially when hard to acess.

You do need a supply of compressed air to use it however.

Most issues with electronics and electricals are of this type how ever,good example when checking a car for it's annual roadworthiness inspection I always test in a real world scenario,for example chech the lights all together not just individually as this will show up bad earth problems.

For instance a bad earth backfeeding power to a reverse switch on a modern automatic tranny can send a signal to the power unit ecu saying the vehicle is in reverse whilst you are driving forwards,believe me the tranny will have a fit in this case and the problem can simply be a poor earth in the rear lights.

The dealer however may end up replacing the transmission trying to fix the fault and could cost you a fortune when it may only need a 5 minute cleanup so always check the basic stuff first as it is more often than not the problem.
