2005 wont stay running

[hiitsme]

have 2005 PT started missing said it was Cam Sensor replaced that ran great for about 3 days and started losing power and wouldn't go above 3000 RPM, ran codes with the Ignition, code P2074 TPS OR ECM its on the 3rd Throttle position sensor and 2nd ECM acts like its not getting Fuel checked Fuel pump Pressure 55 PSI does anybody know what the pressure is suppose to be ? now it starts and runs for a few seconds and quits, anybody heard anything like this ? HELP PLEASE if you can

List all the P-Codes so we can properly diagnose the problem.

Have you checked the wires going to the TPS? There has been cases where one of the wires at the TPS connector goes bad.

Any chance your cat con is getting stopped up? Get a rubber mallet and bang on it and see if you hear any crap rattling around inside.

Didn't you have the same problem last June? Did you ever get it running?

engine code P2074

yes same problem, no not running yet.

Well, I guess you are not interested in answering our posts. Good luck!

Answer Steve and Chuzz. Do what they say. I think your fuel pressure is okay. I can't remember the exact figure they are supposed to be at, but I think it is 55/58. Something in there.

Seems like you keep throwing parts at it. I would start checking the wiring and seeing where you are falling down. Do more testing and less buying.

Your code is apparently for manifold pressure/vacuum leak. From an old Crewzin post:

P2074-manifold Pressure/throttle Position Correlation

CORRELATION - HIGH FLOW/VACUUM LEAK

When Monitored: Engine Running, during all drive modes.
Set Condition: If vacuum drops below 1.5 Hg with engine RPM greater than 2000 RPM
at closed throttle.

POSSIBLE CAUSES

VACUUM LEAK
HIGH RESISTANCE IN MAP (K7) 5 VOLT SUPPLY CIRCUIT
RESISTANCE TO GROUND IN MAP (K7) 5 VOLT SUPPLY CIRCUIT
MAP SENSOR
HIGH RESISTANCE IN (K1) MAP SIGNAL CIRCUIT
RESISTANCE TO GROUND IN (K1) MAP SIGNAL CIRCUIT
HIGH RESISTANCE IN (K4) MAP GROUND CIRCUIT
PCM
TP SENSOR OPERATION
HIGH RESISTANCE IN (K6) TP SENSOR 5 VOLT SUPPLY CIRCUIT
RESISTANCE TO GROUND IN (K6) TP SENSOR 5 VOLT SUPPLY CIRCUIT
TP SENSOR
HIGH RESISTANCE IN (K22) TP SIGNAL CIRCUIT
RESISTANCE TO GROUND IN (K22) TP SENSOR SIGNAL CIRCUIT
HIGH RESISTANCE IN TP (K4) SENSOR GROUND CIRCUIT

Fuel pressure is suppose to be 58 +/-5 PSI

haven't used this Forum to much, if I didn't reply to something it wasn't cause I was ignoring someone.
