Hey guys! need some advice / help! got my car serviced recently and ever since then the car has been running pretty crappy! I cant figure out what it is, it runs fine mostly, but when i let go of the throttle i can feel a vibration coming through the car, can feel it through the drivers seat and through the foot rest where the clutch would be (cars auto), that whole left side vibrates, not dramatically, but enough to notice easily. It seems to get worse on lower revs and i can't figure out what it is, coil packs and plugs are fine, car was running fine before the service. The car doesn't sound the same as it used to either, seems to be more quieter than normal on idle and as i said when i rev upto like 2K and then slowly let og of the throttle i can feel the car vibrate and then become stable again, really weird! HELP!

car: R33 Gts-t Auto

mods: turbo back exhuast, Pod, R34 Side mount, bleed valve boosted to around 9-10psi and SAFCII tuned by RE customs

what the service guys did:

change plugs

change belts (not the timing though)

oil change

auto transmission fluid change

thanks!

Auto transmission issue perhaps. I've been in cars, particularly VN/VP commonwhores and similar year falcons that were a bit iffy on decel. It was as though the box wasn't sure if it was manual or auto, seeing as auto boxes essentially put the clutch in when you let of the throttle.

Might have put in the wrong transmission fluid or something

ye i was thinking the same thing! might have to flush it and put a new batch in! but can you really go that wrong with auto tranny fluid?

      Blue slip

      By GTSBoy · Posted

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?

      You just need a different blue slip shop (preferably one you regularly use as a mechanic), and make sure the coil overs are as close as possible to standard height

      Ethanol Content Sensor - Always at 11%?

      By Duncan · Posted

      yeah the sugar refining companies were pushing for the same in Oz originally, all fuels were going to have 10% ethanol to make them "cheaper" (noting, that the loss in l/100 might be greater than the decrease in price). I guess they won that fight in Canadia
