I have a 93 accord, 193k, 5spd, usually runs great with no probs, on the way to work today it hesitated badly then check engine light came on,,,now it is very hard to start,,,so I thought it maybe needed to be cleaned out,,tried to take it over 3500 rpms and it falls flat on it's face,,,,,Any ideas? I was thinking fuel problem? Thanks in advance for any help, Dave in Texas.
