i have a 2.5 contour, and for about a month it has been having a miss or bogg. it happens only when it is warm. some times it will happen at low steady acceleration and other times it will happen when you floor it. the problem is not undriveable but it annoying. i have changed the plugges , replaced the fuel filterl, cleaded the MAF, put injector cleraner throw, and did a fuel pressure test , when doing a pressure test what should i look for. with the key turned it read 15 psi then when started it read 42 psi. if thats not the problem could it be the injectors or plug wires or coil. if so how can i test these things. please help.
