Was driving 60 miles per hour when car started to sputter and the check engine light started flash on and off. Cabin was filled with a sulfur smell. i pulled over, turned car off for 15 mins. restarted car was still sputtering. After 20mins. of the car being off again, car did not sputtering again until the next day. Engine light did go out, but sputtering.

Had the same problem with my 2004 lx 2.7, code reader said cam position sensor, replaced that $30 @ autozone. 2 screw on front of engine, easy fix and no more jerking

The issue is your Mass Air Flow Sensor (MAF) and more than likely also the Intake Air Temperature Sensor (IAT) which is part of the MAF housing. Both are probably malfunctioning. This can be due to an overused/very dirty air filter, or even an aftermarket air filter (that uses oil on the filter element), or diriving in very dusty/dirty areas.
2 fixes.
1) Get MAF cleaner of Electrical connection cleaner in a spray can from your local auto parts store. Locate the MAF, which is on the intake tube, drivers side, just after the air filter. It is held down by 2 hex screws. remove it (try not to touch the metal with your hands, and DO NOT touch the little sensors that look like wire resistors you will see inside, if you touch them, it will no longer work!), spray it VERY WELL with the cleaner (use the whole can if you feel the need) let dry in ambient air for at least 10 minutes, re-install and like magic, your car will start & run, probably better than before you had the issue. The CATCH IS, this can end up being a short term fix, may happen again after 10 miles, or 20,000 miles, but it will more than likely happen again.
2) Replace the MAF with a new unit, or have your vehicle serviced under warranty, and have the dealership replace this part.

it could probably be a bad engine control module or just bad distributer or plug wires
