dont know whats wrong with my car, help... idle issues

DSM97RS · 05-21-2005

driving downtown tonight my car started revving to around 2k rpms when in neutral. i pulled off the freeway and it rose to about 4k rpms while in neutral and at a standstill. it would slowly lower back to 1100, but if i tapped the gas at all it would rise to 4k very quickly then slowly lower again. after i pulled over i turned my car off to see what was wrong and then it wouldnt start again. we pushed it to a space and it started again but would sputter and do the 4k rpm thing again. anyone know whats going on? my car is on 4th st in mpls and id like it back as soon as i can. thanks for the help

Check to see if your BISS screw fell out. If not there is probably a big leak somewhere.

DSM97RS · 05-21-2005

no leaks (fluids) anywhere on the ground, BISS is the screw on top of the throttle body correct? where can i get a new one if i did fall out? mitsu?

**JET** · 05-21-2005

Yep, only from Mitsu or specialty shops. You could plug the hole just to get it home though. The leaks would be air leaks that I am talking about.

any other theories before i head back to the cities?

If you can't find the problem, give me a call at 651-308-1672 and I will check it out. You are only like 7 miles from my house.

DSM97RS · 05-21-2005

kick ass, thanks a ton. ill go check it out tomorrow.

Where exactly is the car? I could use a new DVD player and some screens

so i got back from duluth thismorning at about 6am and stopped at my car. i didnt see any screws missing from anywhere around the throttle body. i tried to drive it and it drove normal for a few seconds then did it all again. i was able to make it to my house, but still need to find out whats wrong...

ok you really need to do this http://www.vfaq.com/mods/ICtester.html
you will need two people one to pump it up and one to listen for leaks and watch the boost level.
and here is the biss screw

Isn't this going to be completely different because it is an RS? The 420A only has an adjusment screw for the throttle cable if I recall correctly.

Hence which is why, when posting a tech question, all the info should be posted too.

DSM97RS · 05-22-2005

i figured the name would give away all the info ppl needed. its a 97 rs, non turbo 420a. sorry for the confusion.

xluciusx · 05-22-2005

yeah sorry man. my fault i just kinda assume everyone has a gst or gsx...so yeah its completely different

unreal808 · 05-22-2005

The best way to fix it would be to remove the 420a and put in a new 4g63. Seriously now do you have the car fixed? Do you have a bad throttle cable or IAC or a general vacuum leak?

DSM97RS · 05-23-2005

i just got off work and still have no idea what is with my car, so im gonna try to drive it gimp to a shop and see what they have to say. there isnt much else i can do really. anyone think it could be the idle speed control? what about the throttle positioning sensor?
