lol at worst they ruptured your intestines...
Could be bad muffler bearings.
Yeah of course the carbon dioxide and gas affect your body. You start getting bloated of all the bad ingredients too.
Bloated feling could be due to your approaching period. Some people can start having symptoms just prior to their first missed period. Most women don't have symptoms that early, but it is possible.
Check the 92 Eclipse for vacuum leaks. Check to see that all of the spark plugs are firing properly. Check to see that the fuel injectors are working. Either of these could cause the rough start and rough running.
transmission issues, but could be the starter also if you had a rough start.
mass airflow sensor of head tip sensor could also be catalytic converter
Foaming often indicates that the fluid level is too high. Maybe you overfilled the oil? Rough running could be many things. If you haven't changed plugs and plug wires lately, that could be a good place to start. FriPilot
Could be clogged injectors. Run a pint of Sea Foam in the gasoline. No guaranty's but it has worked for me.
crof
There is no absolute answer. Some women get bloated just before a period and they will get bloated just the same but no period will come because they are pregnant so they stay bloated . Some women don't get bloated at all. I don't, lucky me.
Could be in need of a tune up.
When the timing chain is bad on a 2002 Cavalier, the engine could have several symptoms. The engine could run rough, be hard to start, or not run at all.
