What is your question?
we have done a tune up, new coil, new gas cap, new injector, it will run great, start fine for a few days and then acts like a misfire or rough idle on cold starts then after about one minute it behaves normal...been doing this for 4 months.Sometimes it will do it on every start and then it will be fine for several days...???? I notice that when I take my gas cap off there is no pressure release( my other car releases pressure when cap comes off???)

you may have an injector malfunction or the cicuit that controls it.
P0301 refers to a cylinder misfire and it is cylinder #1 check the boot that goes between the coil and the plug it may not have gone on correctly or it may be compromised look for a burn spot on the side of it or if it is torn anything like that could cause an intermittent misfire code.
