why does my 1991 Chevy Lumina that when going up a hill or when it reaches approximatly 65 mph starts hestitating,
when cars get older they do that.
Most likely you have an ignition misfire. Check ign coils, ign wires, spark plugs etc.
Sounds like a vaccuum leak.
I just had my 93 Aerostar 3.0 in for this same problem. My MAF sensor was plugged. Once cleaned, it now runs fine again.
If your Impala jerks while going up hills, it could be low on transmission fluid. If it does not do it on level ground, check the fluid and replace the filter.
this was my own question. it was my coil packs. apparently it happened alot on these models. once i changed the coil packs it was dying after moving from park, but that's because i reset the ecm, and needed to let the car sit in park while on for 20 minutes. havent had trouble with it since. the coil packs are relatively easy to change and you can get the coil pack and the module for about 30 bucks used including shipping! i think the module is really the thing that goes bad. its the brains of the coil packs.
Going up hills doesn't allow engine to "lug" and overheat Going down hills supplies engine braking for safety and will prevent brakes from fading and overheating
If your 99 Chevy Suburban runs smooth, but going up hills it loses almost all of its power and only goes 40 to 50 miles per hour, check the distributor. The cap might be broken or cracked.

They can. The idea that hills disrupt tornadoes is a myth. There are countless records of tornadoes, both strong and weak, going through hills and even mountains.
