These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

    Help hesitates when accelerating

    OK here goes my car sometime hesitates when accelerating really bad then just all of a sudden jumps into the power band, i have no cel lights, most of the time when it does that i would just turn the car off and then back on an that usually fixes the problem.....Do you all think it could be a bad injector? or maybe MAP sensor.

    It could be a plethora of different things really. Does it only happen under load? Going off of what you said I would recommend checking all the grounds, the ignition components like the wires, plugs, cap, button etc and checking your fuel delivery. I bet you could read the stickies and figure it out yourself.

    Good luck.

      Yes it does it the worst under load and when its not doing it, when you are driving you can feel the car missing just a little, i already changed cap and rotor, did plugs(going to check those again today)...my car use to throw a code for o2 but it stopped, so idk i will check it out...thanks for the link

        My car was doing something similar to this recently. It would just die out of nowhere. I'd pop the clutch and it would pick back up but the problem was progressively getting worse. First it would do it once every couple days. Then it got to where it was doing it 4-5 times a day. It would only do it under load...at idle it ran perfect. It ended up being the fuel filter.

          *knock on wood* mine hasnt stall yet, but it does miss really bad then at about 4k it just picks right up out of no where...i think it may be something electrical(maybe) because when i shut the car off and turn it back on it runs fine so idk its weird

            If it's doing what I think it's doing, it's similar to what my car did. I had the luxury of changing out my fuel map, and a richer map masked the problem... Which has me thinking it's the o2 sensor.

            Replace your o2 sensor with NTK/NGK or Denso (NO BOSCH!) and see if that fixes the problem. The o2 sensor doesn't fix itself... so if the light was going on for that, then it's bad. Chances are, the ECU has reached the limit for being able to compensate by adjusting the fuel levels, causing you to bog.

              im going to change out the o2 sensor today and see if that helps any, may also do the fuel filter also it looks like its never been replaced

                Yeah, the fuel filter was the first thing I suspected. I never did change it... but I'm pretty sure that it wasn't the cause of the hesitation. Still, it's a VERY good thing to change!
