My car is hesitating below 3000 rpm's and every once in awhile cyl. 2 will misfire. i've searched this and found that i have a dea sung tps, and plan on replacing it but would that cause a misfire?

i checked my plugs, and they all seem fine.

Any help would be appreciated

Yeah plugs and wires are almost always the cause of a misfire. Check the wires and plus again just to be sure

Not much else simple that you could check other then plugs and wires. If it comes down to it, it may be that your fuel injectors are fouled. Lets hope not.

Except look at #2 cylinder ... too lazy to grab the other image laugh.gif

Pick up a car scanner to verify your code as well! Here is one: Link
