    Hi all... been a while since I've been on. Hope everyone is well and happy :)

    Got a '95 2WD 280K miles. I know what this thing needs... I just want some opinions on what to fix first.

    Cold engine = intermittent hesitation until warmed up. (O2 bad reading at AZ, check engine light stays on)

    Long drives = wont start again until for 20-30 minutes. However, yesterday got gas at 5000' elevation and the 'cold' gas cooled the pump FAST and it started right back up.

    Noisy cat @ high RPM

    So... I know I need a new cat, a new fuel pump, and probably a new O2 sensor since the computer threw that code. What do you suggest I fix first and maybe I don't need all three??? Kinda short on cash.

    I would go with a new pump first, as that might solve the cold hesitation. The computer doesn't look at the O2 sensors when it's cold, so I doubt that would cause any cold start problems.

    If the O2 still doesn't work when it's warmed up, then I'd replace that, and fix the cat last.

    Hope this helps.
