What the hell do you want ? It's an 85k mile car !! Exhaust leak ? Where ? Have you tried to fix it ?
I had an exhaust leak at ~57k miles when a gasket failed. Big deal.
Overheating ? 3 different mechanics say it's ok. From your other thread, it seems ok to me too. Others have posted on that thread and said the same thing.
Stalling on 1/4 tanks of gas ? It sounds like your fuel pump is on its way out. Others can chime in too.
Shifts hard ? Checked your tranny fluid level ? Have you maintained the system ? Regular flushes ?
CEL on and off ? Get the damn codes pulled (free at Autozone) and post the codes here and then we can figure out whats wrong.
If you are a pizza delivery guy as your profile says, then you must realise that this stop-go driving will beat the crap out of your car. However it seems like you like pissing and moaning about your problems more than trying to fix them or even trying to figure out what the problem is.
Regards .....
