94 explorer mania swap

[RubyRanger16]

I just a did a manual swap on my 94 explorer and having some idle issues no I don’t have the manual ecu in it, it’ll idle at 1500rpm but then when I push the clutch in it’ll drop down to the correct idle 700rpm and stay there but the second i release it idle jumps right back up, unplugging the iac keeps the idle perfect, does this sound like I need the 94 manual ecu or is it something else?

So, the auto computer is known to cause idle issues.

That said it also sounds like you have another issue. Vacuum leak, bad IAC, problem with the TPS, you’re gonna need to run some checks
