I have a 96 ek with a b20b with a gsr transmission. When I'm in 2nd, 3rd, and 4th, while keeping the throttle steady at about 10-15% throttle, the car seems to jerk back and forth (like its losing throttle and getting throttle again). It's very slight but it is very annoying. Also, when I'm in 3rd at about 2k rpm and I floor the gas pedal, the car will move slow then all of a sudden kick in and start pulling hard at like 3200 rpm. The clutch (Competition stage 2) isn't slipping cause the rpm is going up steady and when it hits around 3200 rpm, that's when you feel the pull. Any ideas what this could be? I think it might be a bad fuel pump cause my car doesn't start right away every morning until I turn it to the "ON" position for like 10 seconds. Also at idle, it sounds like its bogging out "put put" sound every 5-10 seconds. I put injector cleaners every time I fill up for the past 2 weeks and it still does this so maybe a bad fuel pump?

 

When's the last time you replaced your fuel filter?

 

3-4 oil changes ago.

 

check misfiring threads..theres tons of em.

 

I would check your fuel pump. You might just need a nice little tune up: dizzy rotor sparkplugs and wire.

 

I ran the codes, p1337 came up. It's something with the Crank position sensor. Could this cause the hesitation? The code has always been there, how severe is this code?

 

Fix ALL CEL codes.
