My car is missing really bad down low. It's fine past half throttle, and i have everything up top. But cruising between 2 and 3000 at constant throttle it'll miss really bad then take off and run fine, then miss really bad, then take off. What the hell is wrong? Any help would be great. I replaced the tps (not the problem) and changed the plugs (not the problem) Thanks again

 

You check the fule pump or filter yet? I had the same problem and did a lot of work (time and money) over a $30 (oem) filter.
