Fuel Rail Pressure Sensor...got a question about it.

[SonicBlur]

Are these hard to replace? I think mine is going. I was ripping it down a road and when I slammed from 2nd to 3rd, the car bogged...BAD! But it gathered itself and kept going, it didn't die or anything. Could this be the FRPS or maybe something else? I know I need a clutch soon, but the way the car acted, it didn't seem like a transmission problem.

Probablly the easiest part on the car to replace. 2 screws, 1 vacuum line, 1 wire harness. It is on the front end of the driver's side fuel rail.

Unplug vac line and harness. remove screws. remove frps. replace with new frps. replace screws. plug in vac line & harness. done.

Change it to be safe... but that normally isn't the characteristic of FRPS. We were talking about this last night... what you are describing sounds like an issue that is pretty common in Cobras both stock and pullied cars. You floor it... and the whole car does nothing and then boom your off. I had this happen at the track when power shifting as well... I thought I broke my car. I think it has more to do with the boost bypass, but the only way to see if that is it, is to bypass the boost bypass. On another note, I have heard claims that there is a problem with Ford's base tune, that could be resolved by SCT. I'll have to dig into it again...

so you have to change the oil at the same time then also?

You do not "have" to, but it is recommended. It is possible for gas to get into the oil. I would rather change oil than spin a bearing.
