Rough idle I had my 98 stratus engine replaced a few months ago and this one has a rough idle my friend thought it was the fuel injectors I didn't think so but tried the seafoam anyway it didn't help. It only idles rough when I am stopped and there is no change in the idle if I am using my a/c, heater or anything else. Do you know what the problem could be?

Seafoam is for removing carbon deposits on 2 Stroke engines.
Fuel pumps either work or they don't. They don't 'almost work' and cause an engine to run rough.
You are subscribing to the 'let's try replacing this' method of car repair. It doesn't work and is expensive. You can't guess that maybe the O2 sensors are faulty. You diagnose the DTC trouble codes using a scan tool. That will tell you the state of sensors. If you want the WHOLE story, you buy a $3.5k scan tool computer or call a mobile auto electrician.
Things you can try for free. Clean the Throttle Body and MAF, clean the IAC (idle air control).
Well the timing belt and water pump either work or they don't. So I doubt either part has actually failed.
I think I would want to figure out the running hot problem first since that could cause the other two if its a leaking head gasket.
The sulfuric odor may be too much fuel, a rich condition caused by too much fuel pressure, bad regulator or no vacuum to the regulator . Bad O2 sensor , linked return line , stuck open injector pintles etc. .
It could be something as simple as a vacuum line,but sounds fuel related. Possible pump.get a fuel pressure reading done and if pressure doesn't hold.....suspect fuel pump
clogged injectors I bet with the dirty fuel you claimed you had in the tank. Cleaners will not remove all contaminates in injectors for they tend to get seized inside of them
