Default Re: Stuttering between 1500-2000 Fuel pump?

One time it had a big misfire/ stutter and the check engine light flashed for a second then went out and was fine for the rest of the drive. There aren't any stored codes. Is this similar to your problem Minster?

Mine is a N/A 6 speed with 82000 miles. It has a new CPS (not a Bosch, however). I have not inspected the RCM yet, but that will come while it's down for the winter. What would be a likely culprit? Fuel filter, Bad RCM solder joint, ....?

I've been having this same issue. I will be cruising with light throttle between 35 and 50 and every couple of seconds the car will stutter and then drive normal for maybe a minute, they act up for a few more seconds. Was this ever resolved? I have a spare Crankshaft sensor on hand so I will try replacing that today.
