Ok you will have to have it scanned. It probably has cylinder misfire codes and random cylnder misfires. You could need spark plugs and or coils. The scan will tell you exactly which cylinder is missing. That will cure your problem and remember to change your oil and filter right before you go in for the smog test. Also if the car hasn't been serviced in a while it would be a good idea to replace the air filter and fuel filter.

Possibly. 1st have the battery checked though. Pull it out and have a parts store check it (free service). All the lights may work, but the battery may not have enough 'juice' to crank the engine over. Is there a click, or no sound at all? Check terminals and connection at starter also to make sure all are clean and tight.
If battery checks out as fully charged and ok, then pull the starter and have it checked out. Good luck.

Hi! The problem will surely be the MAF (mass air flow) sensor. If the MAF is faulty then rpm acts unusual. I strongly suggest that you have it replaced for this will break sooner or later. The ups and downs of the rpm is a sign that it will reach it 's break point. Hope this helps and thank you for using FIxYa!

Hello Almo. Most likely these symptoms are caused by either a vacuum leak or a bad Idle Air Control valve or IAC valve. If the IAC is toast (and stuck in one position), it would cause the
same exact symptom as a vacuum leak.
Spraying WD-40 around any potential areas that could be leaking should
help discover if you have a vacuum leak. Using carb cleaner would be
OK around metal, but would further dry out rubber hoses.
Also, on a vehicle that is 10 years old, checking the vacuum hoses
would be a good idea and would be a very likely source of a vacuum
leak. Spraying WD-40 or on the hoses would yield the same discovery
if there is a leak. All said, consider the following:
1. Check vacuum hoses - use WD-40 to help diagnose
2. Check for vacuum leaks around gaskets - again use WD-40
3. Check and replace (if necessary) the IAC valve ( or step motor) -
