alright guys i have a rb25 and it was running just fine but when i left out of town for a week it got drove a couple times while i was gone but nothing major. when i get back i drive it to find that it seems like its lost some of its power. My RPM's usually read around 4500 going about 65-70 now though it runs closer to 5500 RPM's at 65-70 all being in 5th gear and using the stock tach that isnt correct.

I also noticed the smell of fuel which is coming from a small leak on the 02 housing pipe no bigger then an 1/8 of an inch from over grinding to get from hitting the steering rack. it had never smelled so strong or at all before.

also even when the car was running perfect i noticed a clicking noise in the front of the motor right on top of cylinder one. if u guys have any ideas what it could be? or whether to even worry about it?

And lastly just a few days ago i was driving down shifted to pass some slow a** driver when it seemed like a fuel cut but then it would start pulling again. then again fuel cut it kept doing this everytime i would try and hit the gas but did not do it in 1st and 2nd gear? im thinking either to much or too little fuel?

i have a walbro fuel pump, changed spark plugs after it started having issues. also i have thorougly checked the engine bay for leaks and have come up short? i will be replacing the fuel filter soon, also i have a full set of coil packs i got from a friend for free if u guys think that could help? i dont know what else to check im thinking of geting the car dynoed to check if im running rich or lean?
