Hi! I have a Nissan Quest (1999). It's been 3-4 months the gas pedal is getting stuck (not all the times). I am planning to go on some long road trips in next couple of weeks. Is this some thing I should be concerned about to take my van on lengthy road trips? I don't want to get stuck on the road with my family as I have 3 yr old. If fixing this is easy...how can I fix it ( I am a novice mechanic....so please give me detailed procedure...if your time permits)? Or is it some thing I should take to a dealer or mechanic?? Thanks for your time and advice...

Hi, I have a 1996-MercuryCougarXR7-AutoTransmission. I have a couple of problems here: 1. The check engine light glows on ignition, and remains off till ignition is turned off. The light remains on, all the while when the engine is running. --- I tried to read previous posts on this forum and found that I could go to an autozone and get the DTC codes for free. Here are the codes that I found: P0171 and P0174-- the owner was kind enough to tell me what this means- a. Problem with the sensor mass air flow (duno what it means) b. Oxygen sensor defect. c. Ignition misfire. d. Fuel Injection problem -- I am not sure these are accurate but this is what the person told me. 2. I get a check airbag light on when I give ignition, and dissapears when I actually start the engine. I can also see a small flap on my windshield which says "driver side air bag". Other than the above 2 problems my car runs pretty smoothly. I have used it only for a 100 miles though(Just got it).. Please advise.... Thanks.
