So I thought I would solve my typical 240 problem with the funky acceleration crappy idle with a fuel filter. (cars already tuned up)

No dice. The 300zx filter restored a good deal of power up high, but i still expiernce the annoying stumble on acceleration. And not just a little stumble, it feels like im running on 2 cylinders, misfiring. Happens more with the A/C I noticed, just like one post I saw when I searched.

SO now I just bought a new TPS sensor. Im going to install it this afternoon, and post my results. Time to see if i can end the madness!

i had the same problem.. hell, i still do.. i also get about 200 miles to the tank, i had to replace my o2 sensor, spark plugs and spark plug wires, cleaned MAF, cleaned down engine, tried injectory cleaner, all to get about 250 tank. Atleast the idle irregularity is gone. btw, if u buy 4 bosch plugs and an o2 sensor from them, they'll give u $20 back.. so 4 plugs and o2 sensor = 40 - 20 = 20 equals better gas mileage and bit more power

i say its worth a try. email me and lemme know if the TPS helped at all???
