i recently put a used motor into my 1998 honda naccord lx 2.3l 4 cyl the
motor was same and went in without major problem. but on startup engine
starts and high idles well then settles at around 750 with a little wobble
but when throttle is applied the engine revs well for about 2 seconds then
stutters to just about stall then back to whatever the throttle is at.
full presure is at factory max readings at the rail. regulator testsn
perfectly also. i have double checked all conections with no luck. any
ideas especially for testing tps or map sesors with out anything more than
a mutli meter also no errors codes are displayed
