Did you test the MASS with the hairdryer described in the service manual?

I am wondering if the MASS can pass that test and still be bad.

Today I am going to install a salvaged TB and see if it works.


I my travels the only way to really test a MASS is with a MASS you know is good ...And I do this [censored] for a living ..

I dont "think" the pill in the TB would let the idle ever get that high ... Mechanically impossible I "think" ...If anyone have a died 89 TB I would like to bypass the pill and idle it off a hole in the TB plate ....Let me know

Darrel ..Does the truck ever idle right ...?

The thing I want to know is if a car V6 MASS will work in a truck ... Have had good luck with 4cyl MASS and swaping ..Never tryed V6 stuff
