Hi, I have a manual trans. 99 Integra with a B16A Vtec. It has a really rough idle. The idle RPM's will vary from 2900 when cold to almost at zero (without stalling) when warmed up. I also have an engine light on because of a purge flow problem. Could the two be related? I tried fuel injector clener with no luck. Any advice? Also, is it dangerous for me to be driving around with the purge flow problem? Money is a bit tight right now....hoping to get it looked at next week.

Thanks
Charley

 

First thing is to fix the CEL.

 

fix the cel but sounds like an issue with your iac if your tps sensor.. let me know if you interested i could help you figure out your problem

 

Please I appreciate all the help I can get. I'm just starting to get more interested in the guts of a car, and I'm new to modifying. I hope to get her turbo-charged as soon as I fix this other **** that's wrong with her (yes my integra is a girl, only a female would have an attitude like that!!)

maybe try going OBD1 to get rid of that cell - prolly cheaper and will allow you to tune it better. OBD1 dosent check for that purge valve.

I did a swap and no matter what I did I kept getting that purge valve code - so I just switched to OBD1

 

That has to be my issue, too. I had it at the mechanic yesterday and he said that as long as i have an OBD2 with the Vtec, that light will be on, but that doesn't seem to answer the question about the idle problem... : (

OBD2 + Vtec do not equal CEL. BTW, what ECU/wiring are you using?

First of all, tell your mechanic that he's a retard, and never go back to him ever again. Then do a search on how to tighten up and clean your IACV.
