Missing On Idle

[IM-32-FK]

After i sprayed some seafoam into the plenum through a vacuum line, the car started missing badly on idle and making popping noises from the exhaust. I turned up the idle to 1k now so it does it less frequently. What can it be? its a rb25 neo. While driving the car is perfectly fine though.

Well that makes spraying "seafoam" a pretty useless use of time and money....

Maybe it dislodged some carbon and is caught in a valve?

I personally would never use the shit.

Rev car heaps and see if that fixes it

Or spray some other magic cure in there.

Why did you use the cleaner in the first place? What problem did you try to fix?

They aren't really a substitute for actually fixing the problem.

I would pull the plugs and see what they are like,they might be covered in shit.

i did it just to clean up the plenum a bit since i never cleaned it before. Checking the plugs is gonna be a pain because i need to take the throttle body off . The car even misses on low revs below 3000 i realised.

Fair enough. I have never cleaned inside my plenum either. And I never will.

Don't check the plugs if it's too hard.

Bad injector and/or injector o rings caused this problem on my car. If you have the stock inj its probably worth looking into it.

fixed the problem. The place where the spark plugs sit was flooded with coolant, especially the first cylinder. The plugs were also dirty so i cleaned them with a wire brush and contact cleaner. Car is running perfect now. Thanks for the help guys

Was worth the trouble checking the plugs hey?

Glad it's sorted.
