Rep Power: 0 Stalling issue after turboed
I just put turbo on last week. The car stall on me whenever i slowing down. I have to leave the car in gear until the car almost stop, otherwise the car will stall. I thought I was running too rich and i went to the shop to tune it today, and it still stalls. BTW, I have rsx s injectors and safc with return setup. Anybody has an idea what could cause this? Could it be the spark plug? thx

Rep Power: 0 ahh lets see you might check your vaccum lines, that would cause a stall, turboengnr has a point check the fuel presure but that would be the only thing that would cause a stall that i know of other then a boost leek. if you have a boost guage make sure it go's into boost and dosent go up and down.

Rep Power: 261 50 psi shouldnt be too high. Stock is somewhere between 40 and 45 psi. Mine happened to be 42. But an extra 8 psi shouldnt hurt anything, unless your idle tuning it a bit too rich. Check your fuel map in the high vaccum section (25-30 in/hg). If it is left stock, then it will have a very hard time coming down to idle. With the extra 8 psi and the stock fuel map, it will be extremely rich with the larger injectors.

Rep Power: 0 I am positive safc2 is working otherwise the shop can't tune it. Im hoping spark plug will change it since my friend's rsx s turbo has the same problem and he told me changing the spark plug will make it better.

Rep Power: 312 try iriduim plugs, and do check vacuum hoses. i have stalled out in n/al cars cause of leaking or lack of vacuum hoses in the car. other than that your manifold absolute pressure could be too low. ill let ya know if i can think of anything else.

Also, I you guys have IK20 plugs for turbo...then you should be ok with OEM ones, per Denso website IK20 are specs for a stock car....
But I think IK22 should do better

Rep Power: 0 I changed my sprak plugs last weekend. The stalling issue is still there. I am thinking my iac valve might be the problem since I did auto to mannual swap and i still have auto iac valve on it. The part number for mannual iac valve and auto iac valve is different from honda. Hope that is the problem.

I have same problem, I installed colder plugs BOSH Platinum (single electrode) +2 to original specs...
When not warmed up, idle struggles between 600-900 rpm, but when warms up idle doesnt stay. To start a car need to use gas, vacuum is about -30 at idle (normal?)..
You guys keep saying to check vacuum hoses, but which ones?
I only know about two (I will attach pic later)...
I did not have chance to put premium gas, I have 87 now, but can gas octane cause stalling problem?
pls help!

I'm done through basics with this problem.
Vacuum hoses - proper diamer, plugs Bosh Platinum 8 (2 steps colder thaen stock Denso 20)
I think whatever sieetings I have - I run RICH AS HELL - SPARK PLUGS TIPS ARE BLACK. I think something tells ECU to dump extra fuel. I cant figure out what it is.
Also, why on the bottom of the TB, on a side of the butterfly, there is a hole and a little other hole, they seem like to conncet to intakemanifold and have a separate lille chamber thats connected with the main intake manifold by hole.
These chamber and hole in TB do not line up. can this cause an idle / rich mixture problem?
BTW, by TB is dirty as s-h-i-t, covered with kind of black powder - looks like RICH mixture thing...
MAF? TB holes? O2 sensor?
