My 90 has been down for almost a year.I just got everything back together.When the engine starts it idles really high(not sure of RPM).It will run for about 3-5 seconds and immediately die.I just took a look at the TB and noticed the the throttle blade is slightly open and it doesnt hit the throttle stop.I have tried to find where and if its binding but everything seems fine.It didnt come from the factory like this...right :icon_redface:?ANy ideas?I have tried to force the blade shut and it just aint happening.
I dont think it has anything to do with it dieing, but you should probly start by taking the TB off the car completely, and bench cleaning it. Carb cleaner into all the ports, vacume spots, cleanind the IAC, etc. As far as running then dieing, I would start by seeing if the fuel pump is running when the engine is running. It sounds like its running off the fuel from the ignition prime, but then runs out cause the relay hasnt tripped to turn on the fuel pump.
Well,i just went out and vice gripped the TB shut and it runs good.The turbo is making a god awful squealing noise (it wasnt before)and i see little water droplets coming from around the turbo.Also the turbo is smoking after running for 30 seconds.If i could find why the TB is stuck open slightly it would make a big difference.This thing hasnt run in a year and i didnt expect it to run perfectly and the turbo seals were shot before this happened.Thanks for the reply.
check to see if the cables are holding the throttle plate open. if the pump runs at all then the rlay is working.you might want to check the quality of the fuel. when we rebuilt the 3.1 in my sons fiero the car sat for 9 months and when it was ready to run it wouldn't idle at all. it ran really bad. draine d the tank and put in fresh fuel and it ran alot better. fuel is not as good these days as it used to be.
Ok,where the throttle lines meet at the bracket there is the D shaped button you push in and at the same time you open the throttle fully isnt extended out enough and thats whats causing the bind (i hope that made sense).How far out does that plastic slider come out?I have tried to push it in with my thumb and a screwdriver and i cant get it to pop back out.Any tricks to this?
That's the adjustment button for the TV (kickdown) cable. You push the button and pull the cable towards the passenger side of the car to fully retract it. Then you s l o w l y rotate the TB fully open.
Your TV cable is now adjusted.
For some reason i cant get it to move in or out.Its hard and kills my hand to push the button in.I have tried to use a screw driver and a ratchet handle.Talk about frustrating :icon_evil:
Get someone to help you adjust the cable. One of you push the button and the other adjust the cable. I use a very long screwdriver(that's also meatier than the standard sized ones). My current cable is nearly new off of a NA 3.1 and the button on it is super hard to press. I place the screwdriver on the very center of the button to press it down. Once you get it adjusted and drive the car, you may find that the car is shifting too high. Cracking open the throttle body to WOT is basically like doing an "initial" adjustment. I drive mine after resetting the cable, then push the button again and then slide the cable back towards the throttle body a bit to take tension off of it and lower the shiftpoints. Initial adjustments put my car shifting 200rpms too high. Every car will vary a bit due to cable condition, so you'll have to drive it and possibly fine tune the adjustment.
