I just put the 4.0L jeep throttle body on my 97 eclispe 420a and everything went pretty smooth but now my car idles higher than normal to where normal is 750-900rpms now is 1500-2100rpms. im gonna do some twiking to the iac sensor and get new bolts for the throttle body to manifold cause i use the stock ones knowing i shouldnt lol(hard headed). And also im gonna try disconnecting the negative batterry terminal and hopefully it will reset the computer, hopefully. but the increase of respones and power is very impressive so if anyone has any input on the idle problem would be helpful.

Reset ECU. Check for vac leaks. IAC adjustment (depending on how you did it). Check for throttle plate closing all the way.

The usual suspects

ok thanks it was the iac sensor and now is running perfect. Its amazing how much of an improvement it gave. And with the addition of my custom hood scoop its almost like running 3 to 5psi of boost ot 70mph on the interstate. I cant wait to get dyno results for it.
