engine stumble on startup with meth?

scoobiekid86 · 04-08-2008, 10:22 AM

anyone running meth have engine stumble upon a warm startup? i suspect this may be from meth condensation leaking from the nozzle after the car has been shutoff. the amount of meth is probably minimal, but would this cause any long term engine damage?

You shouldnt have that much meth leaking from the nozzle after you turn your car off. what system are you running

warm start ups do tend to be slower since meth vapors enters into your combustion camber. Doubt it will do anything to your motor, you could install a one-way check valve into the line to see if i helps .

I just installed the Snow Performance kit and I'm having the same problem. The system energizes and prims itself when you turn the key on and a small amount of water/meth gets injected into the system, thus causing it to bog/stumble on startup. Where is your meth nozzle mounted? You need to buy the solenoid upgrade to prevent this from happening. It think it's this one: Snow Performance: Solenoid Upgrade

Try holding the gas pedal all the way down while cranking it- it shouldn't start, but it might if enough meth gets into the system. Do this for a few seconds, then let off the gas pedal (while still cranking) and it should start just fine.

I had the same problem.
Maf triggered meth injection - Water/Methanol Injection, Nitrous & Intercooler Cooling - NASIOC
