I checked my spark plugs and they are covered in white residue. So this means my engine is running very hot (lean). Is there an easy fix for this or the only way to fix it is to get a tune. Could lost performance from my injectors be part of the issue. I have a cold air intake installed and NGK platinum spark plugs. Any input would be appreciated.

Probably a clog or malfunction in the fuel delivery.

 

Ya maybe, Ill probably call RC injectors to have them clean and restore my injectors thanks for the input.

 

Is that cheaper than simply replacing them?

 

I haven't checked their prices yet but I think so unless I was going to buy used injectors and what would be the point of that because they could have their on issues.

 

Thought I would throw these two out there as well, have you changed the fuel filter recently? Also, I have seen a couple of H22A's that had malfunctioning fuel pressure regulators. They still worked but just at the bottom end of the allowable fuel pressure readings, which caused the engine to run lean. May thus be good to check your fuel pressure, would rule out these two, leaving only the injectors.
