Got the Drag kit in, never thought I would finish, and took it out around the block, first started it up and the idle went to about 2500 constant, then it dropped down to about 1200 or so, vac reads 12 at idle, and the air fuel guage stays rich constant, no movement, then I drive around the block, boost gauge reads about 5psi at 4k or so, but when I let off the gas it dies, will not idle anymore, and airfuel gauge stays rich, no movement on the drive.
Setup is nonobd electronics, pr3 ecu, lsvtec, drag gen 2 kit
fmu t'd at fpr along with bov and boost gauge
compressor to boost controller to bottom port of tial wastegate.
air fuel gague soldered into the secondary oxygen sensor line.
The only ecu code I have is a knock sensor, code 23, that I left unplugged.

Can someone give me a hand, but it does feel good to have the thing in atleast.
Thanks for your support

 

you should have wired your a/f gauge to the primary o2 sensor not the secondary o2

 

Really, seeing as how they are right beside each other, I did not know that, thanks.

 

yeah, the secondary o2 just checks to make sure that the cat is working. your "true" a/f reading will be from the primary o2 sensor (before the cat) and the reading from the secondary o2 sensor (if your cat is work) will be alot lower

Thanks for the info, this would not have aynthing to do with the idle being high and then stalling out when taken out of gear would it? Also using the NGK plugs supplied with the groupbuy Ben had, gapped to .30.

 

not positive.....but MIGHT wanna try gap at .32, that might help ya out

 

Yeah, I will do that, will that alone cause my car to idle that high, and yet actaully stall out when it is warmed up.

 

rewire the a/F gauge, that will make that work.. If your car is stalling out at idle, possible you have a bad FMU, my friend had one that was stuck open and his car had similar symptoms.. try unhooking the FMU and see if the car drives fine, but dont boost while its unhooked!

 

I'm telling you....this week order at least a B&M fp gauge. That way you at least know what kind of fuel your engine's getting.

 

It is being ordered in the morning mang.

 

Turbo type-R is right about O2 sensors, and also check ALL of your vacuum lines, make sure theyre in their right place, lines that need to be plugged are plugged etc.

 

12 hg is a really low vacuum, unless your at an extreme altitude. Re-check all your vacuum lines and fittings. You should be at 20-25 hg. When I had one of my check valves fall off, my idle was horrible and car kept stalling.

 

Since when does a 91 integra have two o2 sensors? Whatever chassis you are in, none of the non-OBD ecus work with 2 o2 sensors.

Dustin

 

yea, you've gotta have a leak somewhere. I had a couple and it took me a while to find them.

good luck man,

aj

keep us posted

 

Hey Dustin, 91 Integra, Lsvtec, PR3 ecu, has 2 oxygen sensors, I should have mentioned that.

 

they do have 2 02 sensors...my buddy's b16a has 2 sitting right next to each other right after the primaries

 

Jeez, found the prob. atleast I think, Leaky FMU connection, when it stops snowing I will see if that is it.
