idle is too low once warmed up, also warm start no-go....
 
Ok, so I bought my 1988 rx7 turbo-II and was totally stoked. started great, idled around 3000 for a few, then all of a sudden dropped to around 150. If you even step on the brake, turn the wheel, or even blow on the dash (note the sarcasm) it dies. some said MAP, others said TPS. Any advice on how to test these things? And my next question is does my radiator have a built-in intercooler? Someone told me it did yet I have never heard of that.... How do I find out? I'm so lost at the moment.....:scratch: Next is my third question. Once the car is warmed up, if I shut it off then try to re-start it, I have to pull the EGI fuse, crank for 10 seconds, replace the fuse, then start the car with the gas all the way to the floor. Is there a way to solve this? I put a toggle switch on the fused line for now.....

Sounds like there are some serious issues with the car.

Make sure there are no massive vacuum leaks. For example, check the black TID (turbo inlet duct) and make sure it is not cracked or loose.

Make sure there aren't any disconnected vacuum lines.

Check the operation of the BAC valve (see FSM or Haynes manual).

Make sure the throttle cable and throttle plates are not sticking.

A hot start issue could be a number of things, from poor tune to poor compression. The other problems would have to be fixed before this can be diagnosed.

Found one. :blush: One for now, I was searching in the dark with a flashlight, so I'm sure there are more. And I'm sending the injectors out to be cleaned. They are horribly dirty. Things are looking better..... Man, I'm stoked!!!
