Hi all.
Currently on our trek to Argentina and in need of some advice. We are temporarily back into the US (San Diego area).
The 2H in my HJ47 started sputtering a while ago, first only at fast idle during warm up, but the problem is getting slowly getting worse and I'd like to get it solved before re-entering Mexico.
It is now doing it INTERMITTENTLY no matter the engine temperature and sometimes from regular idle up to 1200 or 1300 RPMs.
What throws me off is it NEVER does it while accelerating over 1200 -1300 RPMs.
Symptoms: A sputtering similar to what you get when you loosen up an injector to bleed it.
No apparent leak of any kind. No smell of fuel. No smoke of any kind. Except the black puff you get when tapping the accelerator.
Starts right up and then will sometimes do it, sometimes not.
Water in fuel? I doubt it since the problem is getting worse and I never fueled twice at the same place since travelling.
Fuel filter? I've got a dual filter set-up. I doubt this too as the hesitation probably would be worse under load then idling.
Air leak? Same here. If it would be air in the system, I'd have it all the time, not just sometimes. Plus, chances are the symptoms would increase with load while my problem go away under acceleration.
Note that I've been using a fuel additive (Archoil AR 62) that lubricates and betters fuel combustion. The problem existed BEFORE I started using Archoil and has been present to some extend in Canada, the US and Mexico so isn't fuel quality related.
Any ideas?
Thx.
