Yeah, I lack both an oscilloscope and any understanding whatsoever of how to use one.
I think I’m looking at swapping DI injectors around this weekend to see if that moves my misfires. Do I need to order any new gaskets or anything? I assume new intake manifold gaskets? New fuel injector o-rings? If it is the injector should I just replace the bad one? Anyone have a suggestion for where to get a new one? Sent from my iPhone using Tapatalk

Hmm, I think I might check that bolt (is there a photo you can link me to?) and throw spark plugs at it/swap coils. If that doesn’t change anything I guess I’ll have a mechanic pull the DI injectors and send them out for cleaning. There’s a guy here in Ohio that does it. I was afraid DI injectors would be a pain just because of the pressure involved both from the fuel and the combustion. Damn. Edit: no sense playing with swapping around injectors if I’m paying someone to do it right? I just ought to send them out? Sent from my iPhone using Tapatalk

Send the PI's for cleaning too. Yes, I'd definitely send them out for cleaning. Whether you pay someone to take them out or diy is up to you. I did a lot of reading and video watching before I installed mine. It was nerve racking and luckily it turned out ok. |

DI seals are a pain but kids with aprilias can do them with a tapered punch, a piece of hose and a hose clamp, that's how I do them on VWs. Lightly expand the teflon seal on the puch until it can barely get on the tip, slide it into the groove, slide piece of hose on the seal and tighten hose clamp to shrink it back on. let it rest clamped while you replace the seal on the next injector.
DI seals aren't *that* fragile, they'll survive one R&R. Clean the tips with intake cleaner, give it a drop of oil and sliiiide it back in. See if issue follows, if it does, order one injector and one seal kit, if it doesn't two seal kits to close it back up for good. |

I watched videos of other car's DI and indeed, they appeared to slide in with finger pressure but ours won't. I like your technique of "shrinking" the seal. I'll try that, if I ever have to deal with those b***ches again. Last edited by blsfrs; 07-07-2022 at 09:24 AM. |
