I have a 98 Accord. Today while driving, when it reached 4000 rpms while accelerating, the car would stall until I released the gas and sometimes it would stutter. This has never happend before since I've owned this car. I replaced one O2 sensor a few months ago, and the check engine light came on after replacing that one. I had it looked at again, and it just needs the other O2 sensor replaced. I'm not sure if that's the problem. I spoke with my friend and read a few postings on here, but wondering if anyone knows any ides of what this could be, or if anyone else has had this same problem. The postings I've seen were for 5spd trans. I have an automatic. I'm not too car educated, but didn't know if there would be a difference in situations depending on the type of transmission. I'm going to have it looked at first thing in the morning to get an idea of what it may be. I've been told it could be a fuel system problem, but doubt it would be a transmission problem. Any thoughts or people with the same problem?
