Hey there ya'll. My 96 E320 will at any given time, at idle say at a stop light, give a HARD MISS. Only one time per episode, like you shut the ignition off for a split second. Never sets a code, never does it more that once just out of the blue at idle. All regular maint. done, plugs/coils/filters even three injectors over the last 8 mo/ 4k miles. Is there a cam/crank sensor correlation that the computer reads? It acts like when a GM has that type of situation.......NOW as of this morning its becoming more frequent at idle...HELP!!!<!-- google_ad_section_end --><!-- / message -->

I'm not quite sure what you mean... Does your car just stall while your idling?

I HEARD ITS THE CPS sensor...THOSE USUALLY GO BAD AFTER A WHILE, OR IT MIGHT BE LIKE WHAT HAPPENED TO ME THIS WEEK THAT THE FUEL PUMP WENT OUT..

It might be a dirty MAF that you could clean/or replace, the CPS, or fuel pump. My car is in the shop right now cause the fuel pump is no longer working and while I'm driving it would just stall, when I turn te key it cranks but doesn't start. So if I just wait a bit it will turn right back on when I start it up.

Thanks for the input, Im leaning towards CPS/MAF. Fuel presure checks out consistant at the rail. Im now getting a "LAG" if I take off from light too hard. So somethings not keeping up with my foot!
I will let you know what I find...thanks again.

whAt up Gringo ? Did u change the cps or Maf yet ?

Hey there, CPS is next on the agenda. MAF cleaning didnt change anything, and Im leaning toward doing the fuel pump also since I havent seen where the previous owner had replaced it. I have 213k on it now, the original owner kept great records/reciepts of which I have all.
I be back again to update
Thanks for the post
