Uberoo Posted March 23, 2007 Share Posted March 23, 2007 After a I made a throttle cable bracket. I jump started the subi.IT RUNS,ITS ALIVE!!!and my god is it increadably beastly(legacy Y pipe - cat, so just open headers) Except now it doesnt idle.If I take my foot of the gas it will run about 200 rpm then die or it dies once it gets to idle.That and the crush fitting I got for the oil pressure gauge didn't quite work so I have to find another fitting more like what came in the kit(accidentaly lost one...) then after this I need to wire in my voltmeter and put the interior back together. then it will be:burnout: time edit:it has a huge vaccum leak from the iac because I am missing its hose...

Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 The IAC is located on the intake manifold just under the throttle body?right?Could someone show a pic of it or a better decription of it than chitens gives? Link to comment Share on other sites More sharing options...

86BRATMAN Posted March 24, 2007 Share Posted March 24, 2007 Pic in 5 minutes... Ok so it took more than 5 minutes... Its basically pulling air through the tube going to the air intake. It should open or close depending on how much air it needs to let in to keep the motor at idle speed. You may need to pull it off and clean it with some Intake Cleaner, similar to carb cleaner. And give it a try. Link to comment Share on other sites More sharing options...

Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 ok,thanks.I said pics before you edited those into the other post.Yewa I definatly need to clean it.It is so dirty I thought it was the EGR stuff. Link to comment Share on other sites More sharing options...
86BRATMAN Posted March 24, 2007 Share Posted March 24, 2007 Your motor shouldn't even have egr. Being a 90 model. IIRC only 95+ auto ej22's had egr. Phizinza had similar problems with his brat swap and the cleaning of the iac straightened it out. Link to comment Share on other sites More sharing options...
Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 My idle problems are more severe his is low idle,mine doesn't run unless I have my foot on the pedal(takes really light pressure to keep it at 1000,but with open headers it sounds SO good at 6K!!!!! is the IAC just held on by the 10 mm bolts that are visible or is something else there?

86BRATMAN Posted March 24, 2007 Share Posted March 24, 2007 Should be a three wire plug, two coolant lines, the hose you are missing, and 4 10mm bolts, then the metal gasket. My t-leg is doing the same thing right now. The hose broke off resinator box. Might be worth trying a piece of heater hose to conect it to the air intake before taking it apart.

Phizinza Posted March 24, 2007 Share Posted March 24, 2007 Pull the IAC off, clean it for about an hour, flush it with wd40 or similar until the shaft turns easy with no lumps to be felt in it. What I guess is happening is the throttle body is set to low of an idle and the IAC can't open because it's clogged up so it can't adjust how much air it lets in to fix the low idle. Good to hear it runs.. Now the hard part of figuring out all the issues it has Good luck mate. Link to comment Share on other sites More sharing options...
Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 I couldn't have done it without this board.specically noah(NoahDL88) and brian (monstaru) Im sure there are a few others.To everyone who has helped me along the way with little to big problems thank you.This board ROCKS!!!!

Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 What shaft?I took it of and there really isn't a shaft that sticks out.If I look inside it theres a shaft with a spring wound around it.Is that it?IAC is on a 1990 motor... Link to comment Share on other sites More sharing options...

I think he means the rotating shaft where it lets the air into the manifold. Look at the backside of the iac where it bolts to the manifold.

Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 I cleaned the IAC and the PVC system while I was there.No change.Im wondering if the timing belt might have skipped a tooth because it won't idle unless I have my foot on the throttle.And below 1000 RPM the motor and the entire car shakes violently(no something boxer's are supposed to do) I dont have any problem checking its just I am running an EA81 radiator in a EA82 car(no space and very hard to get in...especially with the powersteering hoses in the way...

86BRATMAN Posted March 24, 2007 Share Posted March 24, 2007 Do you have access to a timing light, you could probably tell a little bit from that. Link to comment Share on other sites More sharing options...
Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 no I dont have access to a timing light.I'll pull the radiator and the covers and see what I can find.The crank pully should be easy to come off,being as I have the DR 5 speed and the EA82 flywheel...ol punch in the flywheel trick..

Uberoo Posted March 24, 2007 Author Share Posted March 24, 2007 Is the arrow on the crank gear for the belt is that supposed to point at the notch at 12 oclock?If so mine is 90* off. never mind,I saw the mark it was only 2 teeth off...Now I cant get the tensioner to collapes...

Uberoo Posted March 25, 2007 Author Share Posted March 25, 2007 after messing with the timing I got it dead on.And to make me happier it was exactly where I started.It seems to miss when I hold the engine at sub 1000 rpm.Im am pretty sure it misses above 1000 but I wouldnt be able to hear it.When I hold it below 1000 rpm I can hear it go bang bang *** bang,bang bang *** bang,etc.so its only running on 3 holes... Right now The O2 sensor is connected but its monitering the o2 count of the air so its running really rich.But I don't belive that could cause a constant miss and lack of idle. edit: oh yea it also runs on with the key off for a few seconds.sometimes I can rev the motor when it diesels.It wasnt doing this before tinkering with timing.

Numbchux Posted March 25, 2007 Share Posted March 25, 2007 I'm assuming you replaced the plugs. how about the wires? I'd get that 02 sensor hooked up! if the AFR's are out of wack...it's not going to run right at all. Link to comment Share on other sites More sharing options...

Get everything right before you start trying to track down problems. +5,000,000,000 These "small" things could be compounding something small like plugs and wires.

WoodsWagon Posted March 25, 2007 Share Posted March 25, 2007 Were you saying that you were running the engine without the 1"dia hose that connects the IAC to the plastic intake that runs from the airbox to the throttle body? These engines run based on the MAF sensor, not a MAP sensor, so having any openings into the air ducting between the MAF sensor and the throttle body will totally screw things up. I know on my 2.5, the engine will start then imediately die if the IAC hose is off. You can keep it running if you try, but it isn't happy at all.

Uberoo Posted March 25, 2007 Author Share Posted March 25, 2007 The last tests were done with the hose to the IAC connected. I have three possible causes that may be making the engine do this.possibly defective wire or coil output.The fact that the O2 sensor is connected but not in the exhaust so it causes the car to run really rich.Possibly the ECU,becuase it controls idle and spark,and I have a missfire and idle issues. First I will get a helper to hold the car at 1000rpm then I will pull spark wires and see if that does anything. If not I will disconnect the O2 sensor,sure it will throw a code but maybe the engine will idle as it won't be flooded with fuel. Finally if no change I will unplug the ECU that in there and substitute it with another '90 ECU... Now I just have to find a helper...If any of those above don't do anything then I will be very stumped... Link to comment Share on other sites More sharing options...
