could a loose tps sensor cause it?

from now on all my answer to these stall, poor fuel econamy, and weird idle questions are check the knock sensor. you might be suprised at what you find.

I have a similar problem kinda.......

I got a code 21 from when I scanned the computer, which translates to a bad ignition signal the scanner says... the Nissan FSM relates this to a code set when the engine dies under acceleration.........

the diagnostic charts start with checking the timing, then checking the ohms on the spark plug wires, then starting to check the mixture... starts with, what I guess is the o2 sensor... it calls it a wierd name... if all that checks out normal it says to check out the Crank sensor and MAF.......

so I'll be running through these diagnostic charts myself and see what happens........

so many people say check all this **** out whenever u have a stumble or bog... and so many people change SOOO many parts and nother every happens....

me I'm gonna go with what the computer and Nissan say........

When I had the same issue before it was the air from the PCV and CrankCase not being put back into the intake, causing the engine to have too little air under throttle.

Also, if no one haas told you this yet,DO NOT USE BOSCH PLATINUM 2+, 4+. THEY ONLY TAKE AWAY YOUR IGNITION POWER!
