[QUOTE="deadpool1, post: 439558, member: 21229"] YES STEP 3 Above the FSM preamble steps to TPS calibration, tells us to use the jeep ISA tool to retract (its plunger full) and even says the TV must be into the TV to TB stops screw. (no gunk there either) idle switch working and WOT switch working. both. the other way is to defeat the ISA, I guess just unbolt it so it cannot mess with the throttle. forcing it by hand the plunger the book says wrecks it. sorry for hills missing, IDK that, so we use only WOT tests, to see if 105HP is real\(spec) only you know if power is fully on tap ,via right foot actions. and maters first. EFI , we tune for power first. full,then with that we fix idle next or last. idle controls love to fail if other base line things are hard failing. case in point, pump in tank only fails,at WOT. (goes weak) the ISA is such a pain then. now i see the chilton only takes JEEP errors and adds more. sad. nothing new about that. [/QUOTE]
