TPS Unit??
 

does an 87 TII have one or not, the guy im trying to buy this TII off of a guy and he says thats the reason its idling funky, but my mechanic said the turbos didnt have a throttle position sensor. so please help me clear this up.

thanks, jake

yes they do

and fire your mechanic

haha ok thanks

And after finding a new mechanic, get a compression check and check the condition of the turbo before commiting to buying.

do i have to take it to mazda to have the check done? or would my mechanic have something to test it? and i cant fire the mechanic tho cause hes a good guy, hes had about 16 1st gens but no 2nd or 3rd gens. he accually builds them to race. so i trust him to work on it. like i said hes just more familiar with 12As not so much 13Bs. and how can i check the turbo? is there a test for that?

You can test it yourself. All you need it a multimeter and a flathead screwdriver.

thats for the tps unit, what about the compression check? is that done by mazda only?

12a's only? What kind of rotary mechanic doesn't deal with all generations? surely the amount of 12a's in any area cannot support my jock strap let alone a shop. C'mon... don't jerk us off.... No TPS? I guess there's no OMP either? Carb only as well? If you would prefer to live in the stone age then you should continue your current strategy to the fullest. Just do a bridgeport with a carburaetor you'll be just fine farting down the road.

well hes not JUST a rotary mechanic, hes only delt with 12a's because thats what hes owned. hes an all car mechanic. there are no rotary specific shops around my area and if there are then i wont be able to afford it. hes the mechanic iv used for years. he works for my stepfathers auto shop, he knows what hes doing. he told me that hes not sure but he thought they didnt, obviously when he pops the hood he'll see that it does, hes not a dumbass. like i said hes owned about 15 or 16 first gens, no 84 or 85s tho, so yes they were carbd only thank you. no reason to be a dick about it, if you had paid attention to the post you would see that hes OWNED them not owning a shop that works on 12a's only. this was a thread for info about T IIs tps unit, not a thread to be a jerk because someone doesnt know as much as the "rotary encyclopedia king" thanks for your help. :fawk:

Whoops... sorry about that.

You can buy a compression checker and test it yourself. You could even use a piston engine compression checker if you follow the procedures below

I'm not sure of the prices, but I don't think that they are terribly expensive.

thanks ill get the tester from my step dads shop, or ill just take it over there and let him do it, hes gotta check a few things on the car anyway before i make the sale final for buying this TII. ill let him know about this method cause it is a piston engine checker so he'll need to know this im sure. thanks tho
