Topic: 22re has a miss

[superyota]

i converted over to efi about a year ago now.  when i did the swap, i left the oblong shaped deal on the end of the cam shaft that use to run the mechanical fuel pump.  last week, i was getting ready to change the oil and decided to take it off before i did.  i took it off, didn't put and kind of a spacer back in to make up for it, and ever since it's had a miss at idle and if i rev it up and hold it.  i don't feel it at all when i'm driving, just when there isn't any load on the engine.  could it be possible that the piece i took off spaced the timing gear out and it changed the timing enough to cause this?  i checked the timing and its at 5 deg. with the wire shorted.  i really don't know what else it could be.  should i put the piece back in?  the only way for me to get the miss to go away is to retard the timing, but then the truck is gutless.  let me know what you guys think.

oh yea, i forgot to mention, i changed the plugs, cap, rotor, and wires and its still doing it.

I've got an efi the gear from an efi engine if you need it? Let me know.

put the  fuelpump cam back on,  its throwing your dist timing off

or  just  move the dist  till it  runs better,  try 8*

Just put it back on man, I left mine on when I converted from manual to electric fuel pump and never had any issues.

i am with the otehr guys, if it wasnt broke, dont fix it.... because it appears fixing it, made it miss.....



also 5* isnt enough timing for the 22re according to my specs

well, i put it back on and the miss is gone. go figure.  i have the distributor turned as far as i can and i can't get any more than 5 deg. out of it.  hey toby, does the gear you have from an efi have an extra washer too that goes with it?  let me know.  i'm interested.  it would be nice to get a few more deg. out of it.
