just got back from a long trip in the 90 740gle wagon. had some worrysome symptoms twice during the trip.

going up long steep hills. now, we are talking up a couple thousand feet at freeway speeds. i get hesitation, like the car is fuel starved. i have my original fuel pump still, is it going bad? could it be as simple as a new fuel filter? this is the only time it happens.

any ideas?

What engine system do you have??? Bf230 (Jetronic) does not have a knock sensor or MAP sensor.

Hi,
I asked this same question in regards to a trip from sacramento to reno a while back(7000+ft up). It turns out that I never took the car out of overdrive(duh),which you should do on hills.

Its just a thought. You never know. Good luck.

Lawrence

i thought about taking it out of OD, but i was going 60-70 mph... felt more like she was out of gas.

Just a thought...check your knock sensor. If it failed like mine did (fell apart in my hands when I went to check it) the car automatically retards the timing. This will cause a hesitation under load, noticed especially at low RPM's in high gears up hills.

Good Luck
