my camaro misfires when iam on the highway going between 50-65mph and sometimes when your at a light it will do 1 misfire. a few weeks ago it would misfire heavy if you left it idleing for awhile and the oil guage would move up and down alittle but when you give it some gas it stops for a little bit. now it only misfires on the highway when your on the gas.

also whats the proper reading for the oil guage? mine starts at alittle past half way and once warmed up it stays alittle past the red

 

i just went through the same thing i think mine was misfiring when the gas was steady but when i pushed down it seemed to clear it up i ended up changing all kinds of things but what fixed it for me was O2 sensors. so you might look at that im not sure. But the oil pressure im not sure about mine always starts a little past half and ends up staying between quarter and half im sure there is someone on here who could help you more but just thought i would give my two cents

 

Sometimes doing simple maintenance around the car will fix that: plugs/wires/O2s/filters/etc...

 

i figured it would be the plug wires i asked on here in hopes it wasnt the distributer but it looks like its not. thats good lol.

 

what size plug wires are the stock ones?
