my car feel like its loosing fuel at anywhere above 4000 rpms i unplugged the tps and it runs fine tho. so im thinking the tps is out of whack, how and can i adjust it to work rite. or should i just take it to the local rx7 shop? thanks --David---
by the way i already did a search didnt find **** in the first 10pages it brought up.

 

That's funny, I did a search and found a ton of info for the tps adjustment. Search for GASP "tps adjustment".

 

search for "tps adjustment 101"

all you need...

or find a post by wayne88na... he shows the BEST way to adjust the TPS (at the ECU)

 

TPS probably won't be in the picture at 4 grand anyway, depending on how fast you're getting to 4K....

Clogged cats are famous for a 4K wall- do you have the stock exhaust system on the car? Are you eating lots of gas?

BTW- thanks red neck

 

If you are seach function challanged here are the "cliffs Notes"

1) Make sure the car is warmed up fully!
2) Find the TPS and shove your multi-meter probes into the two prongs that arent attached to an orange colored wire...(i believe, it's been a while) black and red i think....maybe?
do this on the ecu side of the connector
3) turn on your multimeter and turn the adjuster screw until it sits at 1k ohms.....

If this doesn't work then remove the TPS and check to see if there are large gaps in the range of motion...If so try spraying it with WD40 and set it again, this is a temp fix if it is going bad......

good luck

 

Now as per the FSM, at least for S5's, It says:

"Caution do not adjust the throttle sensors. There is throttle posistion auto-adjust system in the engine control unit"

Whats that supposed to mean? It's on page f2-81 of the 89-91 FSM.

-E

 

That's the high range. You will still be setting the low range.

 

Do a search 3800 hesitation. Read the FAQ. Sheeit I'm starting to sound like Icemark.

 

i have a stock exhaust on it rite now im going to have it taken off next week but i unplugged the tps and it ran fine. im going to try to set the tps and see what happens
thanks for the help by the way ---David---
