Miss on cylinder #3 could be caused by fuel injector or coilpack not firing on that cylinder.

Check your exhaust, see how much pressure you can feel coming out of your tailpipe. Sounds like a blocked catalytic convertor . Other issue would be the throttle position sensor. If you have check engine light in pull the codes

Maybe bad gas?


I doubt it.
Code 316 is a miss noted at startup, 303 is a miss on cylinder 3, 102 is a problem with the MAF sensor circuit and code 113 is a problem with the intake air temp sensor circuit.
The data the sensors are giving the computer are not in a normal range. The MAP sensor is reading too low and the air temp is too high.
I would check the sensors and wiring harness first to see if they are accurate.

Cyl. 3 miss fire code po303


my money would be on the coil cover, especially if it had been a long time since the last tune up. it is certainly worth trying, as this is part of a routine tune up anyways. good luck!
