idle after mods??
i have a 95 sport,4.0L,aw4,4x4. i installed 703's purchased from programbo about a month ago. great upgrade for any 4.0 for under 60$
shipped. nice guy. ran great after that. so the begining of the week i installed a 62mm throttle body. was so happy it didnt whistle. but idle when starting, hot or cold, is way to high. like 1600rpms? after idleing it does come down to 700. also have relearned ecu. same deal. so was wondering if any ideas??also used my tps & iac from my t-body? |
Check IAC or replace.

can always :thumbup1:count on a quick answer from you!! thanks for that. should i swap them back with same sensors & see if it idles correct?? |
Sounds like a good test to me
|
x2 on the IAC. I'd do the swap with the same ones. Should correct it since you've already done the ECU reset.
|
well just swapped back to stock t-body using same sensors.
idles perfect. why would a 62mm body do that? |

reset ecu, then all should be good? |
Take of neg batt terminal for 15 min. Turn jeep on see if the idle settles.
Did you put the iac oring back in? |
yes on o-ring.
|
Is there a hole drilled into the butterfly valve? If you have the intake tube off, look right into the t body. Is there a hole drilled anywhere on the blade.
|
no hole on either butterfly.

Only issue with this is that it doesn't wipe the ECU's memory of your fuel/air trim levels. The only way to do this is to disconnect your battery cables, hold them together for 30 seconds, turn your key to the ON position (DO NOT START IT), turn your headlights on, then off, turn the key to the off position. This is from Quadratec and it's worked every time I've ever had to do it (to mine or others). After 50 warm up cycles your ECU will have figured out the correct fuel/air trim levels.
