Stumble @ 2,000 r.p.m.
My truck has developed an annoying problem and I don't know what could be causing it. Coming back from work I get on the freeway after about 15 minutes of city driving. I take it easy on city streets, and when I hit the freeway I drive a mile or so at about 60 and then take it up to 70. Many times within 2 miles of getting on the freeway headed home, the engine seems to stumble slightly at 70mph--2,000 rpm. It won't stumble under acceleration, only when I plateau it at 67-70. If I give it more gas the truck goes faster and sometimes stumbles and sometimes doesn't at the higher speed. If I don't give it more gas it seems to stumble a little longer. Irregardless of what I do it seems to clear up after about 3 miles at 70mph, and then it doesn't stumble any more the rest of the way home. It generally stumbles at about the same point on the freeway and stops at about the same point.
This is drivin' me nuts.
The strange thing is that it doesn't seem to do this during the daytime on my way to work, only when I come back home, about 11:00 p.m. I'm in L.A. right now, and temps are about 55 at 11:00p.m. Gas tank is full, but that doesn't seem to matter. (edit--I just realized that I go to work at 4-5 during rush hour and often don't get over 45mph on the way in to work.)
Truck is a '95, 2500, 12 Valve. 102,000 miles. TST#6. Stronger valve springs. Pacbrake--(Which is not working right now and I'm not sure why) Automatic, K&N, I use Stanadyne Lubricity Formula at the recommended strength. KDP has been fixed.
Any help & suggestions are appreciated.
