94 Accord vtec drives fine, dies at a stop
I just got a 94 Accord EX that drives fine, but if I am driving +20 and come to a complete stop the RPMs dump to 0 and the car sputters and dies. It starts right back up and then will idle at the stop fine.
|
Been researching and it might be my IACV, anyone have a pic or write up?
|
Yes, go here: https://www.hondaaccordforum.com/for...threads-40780/
Scroll down to the 5th gen section and there is a link. |
Thanks, I pulled the IACV off and the hole with the screen was very clogged. I cleaned it up and put it back on and I still have the same problem. Any other ideas? And no CEL.
|
Might try letting it "re-learn" idle - there is a write up in that same section I linked you to.
Can we assume the tune up items are up to date. |
IACV movement and entry/exit ports needs to be cleaned.
Also clean both sides of throttle plate and bore. Base idle may need to be reset to 550 +/- 50 rpm. good luck |
Do you mean the entry/exit ports on the TB? I cleaned the IACV but I should of done a better job. When I pulled it away from the TB I noticed alot of gunk built up on the screened hole. I thought that if I got rid of that it might fix it, so I will have to remove the IACV and clean it up real good.
|
Yeah, if there's gunk there, you can probably assume there's similar gunk through the IACV itself.
Over in the DIY section there's a post about setting the base idle & having the system re-learn the idle. |
Thanks, I am going to go and surf that section.
|
I went and read up on the procedure to set base idle and re-learning the idle. I just went out to my car and cannot find the screw. Anyone know where it would be on my 94 EX?
|
It's on throttle body entrance near Top Dead Center. Hard to miss.
good luck |
If it has never been touched - there might be a round rubber plug you have to remove before you see the "slotted" head.
|
Cool thanks, I will go check again.
|
I had a d4 flashing light and a CEL so I replaced the VSS and now the car doesn't stall anymore. I was reading about the VSS and read somewhere that it helps in downshifting when slowing down. It makes sense to me that with a bad vss the car would die when coming to a stop. The idle is fine and doesn't drop like it used to.
|
Glad it's fixed. Probably VSS and IACV cleaning both improved idle performance.
good luck |
