Engine Performance problem
2002 Nissan Sentra 4 cyl Front Wheel Drive Automatic 140, 00 miles
I have a 02 Sentra w/140,000 miles. About 2 months ago I began to feel a slight inconsistency while accelerating & when I came off the gas. The problem has worsened severely. My vehicle now eats gas, has severe power loss & has allot of trouble climbing hills. The car cannot be driven at this point. The vehicle idles perfectly & the problem only happens when the vehicle is being driven. We have checked the catalytic converter & it's fine, checked all hoses for leaks, checked the fresh air intake, & air filter. No problems found there. My question is what could this be? I took it to my local Nissan dealership to have it diagnosed but what they advised as the problem doesn’t make to much sense & the price is outrageous for the repairs over $1,000.00. What could the problem be? We also replaced the spark plugs in Dec of 09 & they are needing to be replaced again. Thanks
have the same problem?
