What causes a 2002 Oldsmobile alero to lose power climbing hills?
My alero 2.2 lt engine, does not want to climb hills;unless you are traveling at 75 or above. if you are at 60 and try to go up a hill you will drop down to 40 ish sometimes lower. we have tried several things and nothing. sometimes when it is losing power the temperature tires to run hot as well. riding it on regular roads with small hills no problem runs like a champ but going into hilly areas with mountains it has above mentioned issues.
spark plug wires
trial and error is beginning to be a bit expensive.. lol..
