My tps plunger sticks when depressed all the way. Could i spray wd-40 or something similar, kind of down into it without damaging anything? I think I can but my logic always seems fuzzy.

 

ohh yeah 88TII

 

I tried for a while. Stop open hood, masauge, tweek, twist...would go for a while.

Replace the TPS! Mazda only about $475.

I got a good deal $50 for entire throttle body, but make sure if you do that the IPS is attached.

I never disected it to see what is in side.

Anyone have picture of TPS guts?

 

Use some electrical contact cleaner on it. I had the same problem. Unfortunaly mine was not only sticking, but was throwing out bad voltage signals. Thank you mazda for charging me 320 dollars

 

yeah i used some 2-26 electrical cleaner lubrication type stuff...worked good

 

If you plan to buy a new TPS do a search, "Brad89RX7"
and you should be able to get info on discounted Mazda
Parts. I had a thread on, "How much my new TPS cost!
