yeah that is what I had before I switched it, then got a P0401. and for good reason. I opened up the throttle body, and it was a carbon mine! solid carbon through all the passages, up until where the inlet was, that was open.
I blasted the passages with carb cleaner, the hole in the throttle plate was clogged as well, blasted the carbon plug out of there, I sprayed and scrubbed that with a toothbrush until it was clean, I had to chisel out the carbon from the passages with a small screwdriver, I disconnected the EGR valve, blasted cleaner up the passage and it ran out dirty and chunky for a bit but then it ran clear, scrubbed the rest of the EGR passages with the toothbrush, blasting it with carb cleaner, got it all opened up, finished cleaning the throttle body, bolted it up, and it feels like it runs better than before. might also be the fact that I also cleaned the layers of carbon off the throttle body as well though.
BrApple you are the man!
