95 se 5 speed with 88000 miles have tried everything and have no low end power. I have 16 inch Einkie 5+ wheels with 215/55/16 Yokohama yk420 tires. Have replaced the knock sensor all six coil packs. Use 91 octone always. Cleaned throttle body many times, and have went over the 60k maintaince many times as well. Searched till i turened blue on here for something ive missed and found nothing yet. PLease help....

 

no low end power.... thats it? thats all you are giong to tell up WTF?? its like going to the doctor and saying I have a pain... little more would be nice

 

ok Im sorry i can barely chip the tires in 1st gear for starters. In 5th gear the slightest hill i have to floor it just to barely hold the speed limit. Gas miledge is very bad as well. Starts fine Idles fine I have no idea what it could be??? If you nedd more info let me know please help me!!!!....

 

check maf, plugs, fuel filter

 

fuel pump? pulley belts? filters? pulleys?

 

O2 sensor?

 

Injectors maybe? Is the car misfiring?

 

Clogged exhaust system, possibly your Catalytic Converter.

 

The car isnt misfiring or running bad idle wise. How can i find out if the exhaust system is clogged? And i get no codes either. Thanks for everyones help so far.

 

Listen to the exhaust, you should hear the individual cylinders firing. If your tail pipe sounds like hushhhhhhhhhh very smooth with no puttering then most likely your cat is plugged.

 

Ok sounds like the exhaust is just fine can hear the cylinders firing. The fuel filter is maybe 5000 miles old. Havent checked any pulleys do i need to the belt looks good. If it was my fuel pump it be messed up all the time wouldnt it?

 

If you have a K&N filter, clean up the MAF heater element with some Isopropyl alcohol to get rid of any excess oils that may be collected on it.

If using gasoline with MTBE, wwitch to a fuel that does not contain MTBE and then run some fuel system cleaner for a few tanks of gas. MTBE leaves behind a lot of carbon deposits in the engine.

Make sure you are using the OEM type NGK spark plugs. Those so-called "split fire" V prong plugs or a Bosch "+4" type plug will result in some driveability problems.

High inflation pressure on the tires especially stiff-sidewalled performance tire can diminish low end response if your alignment isn't spot-on perfect. (At any rate, the toe-angle tends to change slightly with speed).
Keep the pressures around 30PSI. Stock wheel weight is around 16 pounds. If your Enkei wheels are significantly heavier, you will lose some response. If the wheel offset is significantly different(wheel sticks outward significantly more than OEM), throttle response will also be diminished.

Check out the O2 sensors and knock sensor. At the very least, make sure there are not excessive amounts of deposits clogging the O2 sensor pores. You could have the dealer technicians do a functional test of the O2 sensors and clean them if necessary.

 

Its most likely the fuel filter or injectors.

 

ok I will take a look at the tire psi, I think they are at 34. The enkie wheels are like 22lbs each should I get lighter wheels like the 300z 16in wheels or go back to the 15 inch wheels?? I have run plenty of the BG44K thru the system and injectors. Could the O2 sensors be bad and no codes be present?? If so which of the three, or where to start at?

 

please advise further....
