so within the last few days my engine has started running a bit raggedly.
The idle is at about 800, and both idle and neutral rev sound normal.
however when in gear, it is really choppy and i can relate it to the baseball card on a bike tire. Changed the plugs and nothin changed.
Gonna check the ignition coils as soon as i have the time.
what else should i be checking.
to clarify it is only noticeable when in gear.
Is that the sound you hear coming from the exhaust or is it a clunking or ticking sound coming from the engine?

I really don't see how something making a grinding and chattering noise can be a fuel issue if you're not getting any codes and your engine is running fine in neutral and at idle. Drain/change your trans and t-case fluid. Stick your finger in there and feel around for any metal or gunk that may have gotten in.

Grab an ohmmeter and check your sensors; make sure the coolant temp and IAT sensors are reporting the correct air and coolant temps to the ECM. If they are bad, your mixture will be way off and could cause these issues. The IAT should be around1-2K Ohms I believe, and the coolent temp should be under 1K on a warm engine .
Either of the 2 sensors should measure around 1k-2k (ish), when warmmed up. I installed a 1.2K resistor in the iac harness until the sensor I ordered came in . The engine ran 95% perfect, (which was at least 50% better than before!). My original IAC sensor measured 300K, which said the temp was around -40F !
Does it run any different between cold and when its warmed up? Does it happen at idle or when you are accelerating? Backfiring and missing is a timing issue related to sensors. Make sure you read the right temp sensor. The one you want to read is in the front of the engine on the thermostat housing. Clean out your throttle body and your IAC.
