Hey guys ive notice a strong fuel smell in my car everytime i hit the throttle? ive did some checks like checking the engine for any smell or leaks but douldnt see any, so i go to look under the car for leaks on exaust etc... still no sign, so checking to see if they are coming from the air vents while window is up still no sign, but once i drive my car with windows down, the strong smell just appears?

any ideas?

cheers

Hows your fuel economy?

I sold my old R33 a while back and it had a similar problem, (could always smell fuel but could never find any leak) the guy who bought it off me said when he got it tuned the oxygen sensor on the exhaust was faulty and it was causing it to run too rich using too much fuel. If you have no fuel leaks and it's not been replaced in the last 40K thenit may pay you to replace it.

had the elecrican down the block from me have it checked on the diagnostic but hey didnt notice any faults or what so ever on the o2 sensor? also i had my ecu reset before i got it on the diagnostic??

Check fuel filler, fuel tank breather lines, etc for perished hoses.

mechanics have tried looking for leaks through the fuel lines etc... but had no clue?

*note* ive got a dump pipe straight of my wastegate welded onto the manifold? could the smell come from the dumpy?

Fuel filler, from what i've read here. A mate of mine had the same thing (very strong smell when cornering) and it ended up being a crack in the rubber surround of the filler... which is added when complianced. (at least on his car it was)

i have the same prob with mine, i noticed a while ago wen i turn the car off i could hear a hissing sound from the fuel cap and the smell seems to be coming from there, going to put a new cap on it now to see if maybe thats the problem, u no, the cap not shutting properly, mite resolve my other acc issues, maybe im losing fuel pressure.just a thot, check it when u turn ur car off, listen to the fuel cap and smell that area.

    • sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving. 
    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
