Bogging Down Under Acceleration?

Hey Guys,

ok so im fairly new to skylines, i hav and r33 with an rb25det.

It has recently started to act wierd under acceleration but not all the time and not all the way through the rev range.

So for example if i pull away from the lights quicker than normal but not flat out, first gear ok change into second it will be ok as i got up the revs the all of a sudden it will stop accelerating almost like its bogging down, foot will still be down on accelerator but nothing happening. so il clutch down and blip it a few times to clear it up then its ok, then change into third and it will do it again at roughly the same rpm????

But it does not do it all the time, maybe half the time. Im not confident but i was thinking maybe running lean or rich at this point just to a fuel/air sensor or an air volume sensor??

Is this common and specific things to check or clean??

The engine is completely stock apart from a HKS pod filter and a turbo back exhaust, which were both on the car when i bought it 2 months ago.

Greatfull for any info advice or solutions cheers :yes:

What kind of boost are you running?

Do you know what rpm it does it at.

When it happens do the revs keep climbing or do they bog down much like the car does.

Could be clutch slip

Could be R&R rich and retarded from running to much boost.

Also could be misfiring

so dry joints on these plugs is a common issue??

It sounds and feels to me like it could well be this or something very similar. Unfortunatly i dont know anybody else near me with a skyline.

But i may try cleaning and re inserting all the plugs??

I have not had any kind of engine warning lights come on, would a sensor issue not trigger this? ie if the afm sensor is playing around with the mixture would the exhaust egr sensor not read faulty??

      Well, fun day was had, I finally found a house that will do me just fine, 1980's brick build, but with full fresh renovations, plus new colour bond fencing all round so puppies are incoming 🐕, and water tanks for the garden, and it's located in West Goulburn..... @Duncan 🫡, so day trips to Wakie to watch cars going Zoom will be on the cards In the end it cost well under my budget and was actually better than alot of the more expensive joints I was looking at, it is in a good area, close enough to the shops, public transport, and the Wollondilly River Weir,  and the great walking paths along the river, but far enough away from town to see minimal traffic The deposit is dropped, the conveyancer is conveyancing and I should get the keys in a week or 2 as the property is currently unoccupied  As with everything I own, I'm doing up a modifications list, as it doesn't have solar, that is first up on the big list, all of the panels and enough batteries to keep the joint warm, or cool, followed by a largish carport out the front, the small list, which will start as soon as I have keys, is some security stuff, like cameras, screens, and the usual "crazy prepper" additions that weird old people like (mouse holes to stick shot guns out of, and the usual man traps that the average person installs for the unsuspecting and unwanted guests 🤣) The gardens front and back are OK, but, not to my standards or liking, so landscaping will be a fun job to start getting into, so when spring is sprung I'll do a heap of planting, lots of natives and vegetables is the plan, the old owners were more "Old English Garden" type, so basically Roses and other weird looking things that are destined for the green waste bin One thing that is staying garden wise is a nice established hedge out the front, it is about 5 foot tall and covers the whole front of the property from prying eyes As for the car hoist, the roof in the garage has some height to it, but, I'll need to get an installer out to see what can be done, width wise may be a issue, but my building inspector will be getting back to me over the next week with his recommendations  Small, but cosy

      I tried to get in contact before I went to QLD you didn’t respond, then I tried to contact you in r31 club.  I thought you fell off the earth or something haha.  I will grab it off you but unknown when I will be up that way

      I think that might be in the question. He is going very low, and I think the standard GTR ones are simple tripod joints (like the rear NA/S chassis ones), not proper CVs (like R chassis turbo/GTR ones). Proper CVs take the misalignment better than tripods.
