Yes, notice when the weather gets hot. My car acts funny as hell.
Rpm drops below Idle Level and to Zero! at Stops.
-------or After Boost, my car acts funny, wanting to stall. Psi Gauge fluctuate all over! Oil light turns on.! And yet, eventually Stalls..

Compression is good. Cars running strong right after Few Long cranks, it will start back up.


Maybe :
-Intake is receiving Hot air, and will richen things up? or
-IACV? *(just clean it with Carb Cleaner, good or bad idea?)
-Vac Leak,. I doubt it.
-Wg Dump and Air gets Sucked back into intake! (Bad Air indeed)!

Anyone had any solutions? Lots of thread with no anwsers.

Anyone?

I got a honda

im having the same problems...overheating, random stallingness...new motor time...

nerdsports

wow. i'm not alone.

lately it's been idling real low (has good compression btw) and it's been overheating after long drives or some boost.

AspectIndustries

My car isn't overheating though. Temps stays same.

uPpers!

You should check thermostat etc on your car. Or your Tune. ^_~ Or even your Fan, make sure it does run fully when needed.

My car and brothers car, did this, the lines are pooop.! So we had to re solder new lines for Fan.

i've had idle issues w/ hondata until i disconnected gas tank fuel evap line and switch that goes to intake manifold. i don't know if uberdata would have same problem.

I might try this out, wont hurt. Was planning to take the Can out anways. I'll let you know if this may help. Weird though.

Curious, whats the switch for? I notice OBD1 gsr motors dont have it. Its a obd2 kind of thing eh?

vtec.dc2

switch is a valve that opens to let gasses through, making the car run rich at idle.

AspectIndustries

That might be my problem. Its a tad bit rich all a sudden at idle. Not sure if thats it~

redturbosi

i had this problem and got my car retuned then no problems. kenny tran showed me the prior tune done by another shop and the air fuel ratio were off the chart. try retuning.

blackeg

ive noticed that more than occasionally i will run real lean after boosting for a short period. perhaps that is what is happening to you. ive also recently had some problems wiht my idle and uberdata. it just came out of no where as yours did. good luck with the fix

where is it exactly located?

m R g S r

it has a vaccuum line coming off of it going to the intake manifold, and the other goes to the canister. Useless on obd I cars....because the ecu doesn't even have controls for the valves.

ginoboy1978

I unplugged my evap purge solenoid on my car and it idles perfectly now

Just unplug it....... since you're obd1, there will be no CEL.

DAN

AspectIndustries

Sure will. I will try it in a few minutes. Thanks guys

M.A.R.C.

that lil black solenoid looking thing on the fuel rail... try unplugging the plug that goes to it. worked for me.

done

i have the same problem, but when i unpluged my purge valve, it through off my a/fs..

i think because i tuned with it pluged in.
