ugh...im so stupid. Typed that post with a few beers in me. You are right hissin......basically switch the closed loop to open loop and vice versa in that post. Sorry bout that :damnit:
I went to Hackettstown Ford today and ordered a new IAB,it should be in next week.97 beansjrichker said:Check & clean the IAB electrical contacts & the 10 pin connectors too. If that doesn't fix it, I would look into replacing the IAB. The cold stalling is a clue to a non-functional IAB.
Tuff02Ranger said:I've tried just about everything listed here, and I still have a surging idle. But mine goes from like 700 up to 1300 RPM's. I'm also running very rich. My car was fine before I added the supercharger, 255lph fuel pump, and 30 lb injectors. Also went to a 76mm MAF. If I unplug my MAF, it won't surge anymore. I've cleaned the IAC and throttle body and still no luck. My brother thinks that putting in a Kirban FPR will fix my problem. Does that sound right? Between regulating fuel pressure and adjusting my timing, should that fix the problem, even though unplugging the MAF stops the surge?
Yeah,I would try turning the MAF,its worked for me.Turn it 180 degrees towards the motor.jrichker said:Try cleaning the MAF element & then "clock" the MAF to see if changing its position helps any.
don herberto said:Alright,
I'm starting to have the same issue with my Stang and I think I have found the problem. I'ts most likely the IAB and I want to clean it out, but I don't know what to use.
What are you guys using?
I would use some RTV sealant since you are mating a water jacket (TB water cooling) to a part that has engine vacuum.don herberto said:Here's a question that is a little of topic, but deals with the same situation. I pulled the IAB last night and cleaned the ports on the side of the throttle body. I put everything back together and now the surging idle is worse.
While I was cleaning, I decided to pull the throttlebody and the gasket was horrible. I figured this might be a part of the problem so I headed right out to the parts store and bought a brand new gasket, but this is the thing:
Do I need gasket sealant for this application?? I could not tell because everything got soaked in coolant. The guy at the shop said I should get it and sold me a tube, but I thought I would get some feedback before I started.
Any hints??
Is the X3Z puter not a cobra unit? If so, it seems to me that the puter calibrates for 24# injectors itself (in case an issue pops up for you Bert).BERT306 said:I just found that i had a X3Z computer in my 90LX, not the A9L. Had to get a calibration tube for my 76MM C&L
MAF to match the X3Z. Runs GREAT now!!!
Jrichker has some wonderful write-ups he has posted on peoples' threads. I would search each term above using the search feature, or search JR's old posts. You should find what you want.mkkrs1 said:If you replace the TPS or IAB. do they have to be set or is it a simple remove the old one and install new. are there any checks to perform to see if the TPS or IAB are still good before you purchase new ones not needing them.
