[QUOTE="93Cobra#2771, post: 9342801, member: 4599"] But, you can actually get an older style code puller for under $20 bucks. You absolutely need to get the codes pulled, as it will help head in the right direction. Something as simple as an O2 not switching could be the issue (would ping a code) or something as complicated as an O2 reaching max fuel adjustment (vacuum or exhaust leak) can be found that way. Could be something mechanical, such as a burnt valve, or dirty maf element, etc. Lot of "could be's" happening, so we need to start eliminating possibilities. That starts with pulling the codes. :D Fuel pressure is a bit low, but not enough to cause what you have. [/QUOTE]
