I was tuning my sentra and after replacing Rotor, Cap and plugs I proceeded to replace the fuel filter. After I did the car will not accelerate past Idle, as if not enough gas was flowing through it, I checked for bent lines (since I was working on a tight space) or any vacuum lines that might have come off but every thing appears to be fine. Does any body have any idea what might be wrong? Does it need to be bled? Any suggestions will be greatly appreciated

Thanks in advance
:(

Was it put on backwards? Not sure if that would cause blockage though. Or maybe you unhooked the tps by accident?

No it was not backwards, in fact I took the old one and put it back in case the new one I had just purchased was damage. As far as the TPS... What is the TPS?

Throttle position sensor, it's in the vicinity of the fuel filter (well sort of, it's on the throttle body right where the rubber meets the metal) and who knows, maybe you brushed your hand on it and it came unplugged....but it's a long shot.

Thanks Centurion, but not, that is not it. Does anybody know if maybe air is in the line and that could be doing it? Or perhaps it is supposed to have or be under pressure and it has lost that pressure...How do I re-place that pressure back on it. Is there some kind of inboard computer that must be reset...How?

Thanks again

Jose

If you did all the tuning at the same time it's likely it could be something else besides the fuel filter causing it. Did you do the maintenance one at a time and drive it before you did the fuel filter or did you do it all at the same time? I guess that's why they say do everything piece by piece in case something goes wrong you can diagnose what it is right away.

Thanks UnderDog, but unfortunately I did not do and test each individual things. Regardless, if it was the plugs it would be backfiring, if it were the rotor or distributor cap it would not even start, now it does start and idles but it will not accelerate nor will it have any power. I was hoping that brainstorming on the forum with all the people reading maybe someone would had the same thing happened before and could share the solution.
Thanks any way

I had a similar problem a couple years ago with my car. After changing the cap & rotor that i purchased from a local auto parts store my car had no power and wouldn't rev past 3000 rpms i was like wtf. Then after almost an hour of trying to figure out what went wrong my bro and i started back tracking our steps, we double checked the cap it looked fine then the rotor, after further inspection turns out the rotor was defective. We put the old nissan rotor back on and the car ran perfect again. Bottom line please only use quality nissan oem tune up parts on your car. The berk-arnley cap & rotor that i purchased was crap and cheaply made, which made my car run like shit. Since then i have only used nissan caps,rotors and fuel filters on my car. Live and learn!

Well, changed the rotor and cap...same thing.
I bought a couple of bottles of Pyrol fuel injector cleaner and pour it o the gas tank, thinking that may be while moving the fuel filter I got some dirt clogging the injector. It appears to be working, but I'll wait till tomorrow before counting my blessings

I'll keep you posted
