Okay I've got an 02 EP3, it's virtually stock, with the exception of a muffler and a short ram intake. The car is hard to start, and has an issue with rev'ing but idles perfect.
So what I've done so far;
Took a scan tool to her (stock ecu no K-pro), and I get two codes; P1156 (which doesn't even show up as a Honda code), and P0141.
So when I look up P0141 it's the secondary o2, I really don't need this o2 correct?
Secondly I start a datastream and notice the TPS is at 10% when no throttle is applied, and goes to 91% at WOT. Hm, weird, this is for sure an issue, but I don't think it'd cause a low RPM studdering.
So I've done a compression test, and I got 200, 200, 200, 175. Added oil to the last cylinder and compression went up. I went ahead and rotated the motor to TDC, and pulled the valve cover, and timing is dead on.
I've replaced; coils, plugs, crank position sensor, and I'm about to replace the throttle body. Everything that I have done I've verified that it's not the issue.
So the car sputters at low RPM's, doesn't show any misfire codes, idles pretty good (with the exception of some valve tick), timing is dead on, I've already replaced the main ignition stuff including the crank position sensor, and I still can't figure it out.
Any ideas guys??
