Misfire Problem

[RS-V AREO]

Hey all

Still having problems, i have a intermitent misfire problem, it was kicking into limp mode every now and then. So try and fix it i changed the coilpacks, coilpack loom and the afm, only other thought is injectors? Could that be causing it?

Any help would be great

Have you dropped the boost to see if it goes away?

Without a list of mods it makes it hard to suggest much. I would recommend finding the issue instead of throwing parts at it.

would be easier to help if the spec was listed

turbo

fmic

injectors

etc.

what you got ?

[scotty nm35]

I have turbo, injectors, fmic. I even had them when the car was stock.

I hope you have changed the plugs. .

[RS-V AREO]

I have stock turbo, 3inch cat back, stock injectors, fmic and a bleed set at 10, sparks were change a few months ago and were gapped a .8 instead of .11 to try and fix the issue.

What plugs did you use? What heat range?

Have you ever checked for boost leaks?

[scotty nm35]

Boost leaks, or your gauge could be faulty. Mine used to read 3psi out.

Pressure test the intake and drop the boost to minimum and see if it goes away. Some ecu's just don't like high boost.

Time for a tune?

[RS-V AREO]

I intend on getting a tune soon, i have platnuim plugs in at the moment. I went through the whole system a few months back to check for leaks and i couldnt find any i changed all the clamps aswell. Ill take the boost off and see if that changes it.

I did have an adverage mechanic fit a check it awhile ago but they screwed around with my turbo hoses and now half them arnt even hooked up.

[Ben C34]

You haven't answered my question on what heat range plugs. ....

Never mind.

Don't waste you only with platinum plugs. Coppers are the go.

You can visually check all you want for leaks,but untill you pressure test the intercooler pipes you don't know if you have any boost leaks.

How many hoses do you expect to be connected to your turbo? As you mentioned mechanic put half back on.

So instead of putting the F piece back on the bypassed the solenoid and just put the intercooler hose straight to the turbo and they had the boost sensor and another hose mixed up for what i found with a vacum diagram i found for a neo.

process of elimanation, and frustrating, mine turned out to be crank angle sensor
