Question about 2002 Dodge Intrepid
Recently serviced (oil chg, filter, oil, transmission, water levels good) belts appear to be good & working. Gas cap secure.
There are a number of reasons the check engine light illuminates. Chances are unless you have a scanner for the car you may not be able to clear the fault on the check engine light - most mechanic shops can read the codes and give some idea where to look first they can also clear the error. Most commonly it is due to a miss fire. Start with spark plugs work your way though to ignition coils / leads (distributor cap depending on your car) - this will fix most problems. If all this checks out start considering fuel injectors after this is usually other sensors / wiring but hopefully by now the car is all good.

Increasing the weight of the oil by a shade will get rid of the problem, and adding a high-zinc motor oil will eliminate any possibility of sludge in the pan (with proper oil changes). However, as mentioned before, it is a band-aid fix. It will work indefinitely, if you are diligent with changing your oil every 3000 miles. Use 3.8 quarts of Rotella T 15w-40, add one quart of Lucas oil stabilizer, and use a WIX filter with an anti-drainback valve (which isn't really necessary since the filter hangs upside-down on a 2.7, but it's a good habit to use one on everything you drive). Do not use a Fram filter, Valvoline oil, or STP... or anything else. The three I mentioned above are the only ones to use, and DO NOT USE SYNTHETIC OIL/ADDITIVES. I bought a 2004 Intrepid for the whopping sum of $250 that had the oil light/idle/low RPM issue because the owner was told by Sternberg Chrysler Center in Jasper, Indiana that the engine was going to grenade in short order. He wasn't going to pay them in excess of $2000 to replace the engine. I've put tons of miles on it since, and absolutely NO sign of the light, even now with the 2/1 Oxygen Sensor bad (which lowers the idle down to 600 instead of 750-800 where it should be). I'd trust the car cross-country. It's an expensive oil change at around $40 instead of $20 with cheap components, but what's saving your engine worth to you? A heck of a lot, I'd hope!

SOURCE: Will not start
Most likely is the timing belt. Unfortunitly, I believe this maybe a non interference engine, meaning you may have bent all the valves in the head.
This maybe a costly repair. Have it checked properly by your mechanic

Is it the "oil change req." light? Your owners manual will have the process for reseting the oil change light.
If it is "service engine soon" light, the vehicle will need to be scanned with a professional scanner.

If it has never had plugs changed, i would suggest it. It can make a big difference.
Labor time is .8 hrs + 6 plugs = $80 - $150.
Take your car to a parts place and they will usually check and clear your light for free.
Firestone likes to up-sell everything, $650 is way too much for a basic tune up.
