Background info: I've had the timing belt replaced, I've replaced the IAC, vacuum hoses, new plugs & plug wires, cleaned EGR valve, had alternator tested - it tested good, replaced a/c & heater control unit. Local mechincal adjusted base idle.
The problem starts when anything puts a load on the motor - the a/c is the greatest drain. The RPM's dropped drastically when a/c is turned on. When alternator was tested I did notice a 19 amp drain on the charging system when the a/c was cut on. It went from 69 to 50 amps. Is this normal? I've pulled out the relay for the compressor and it still pulls down the motor with the a/c on. I've taken the compressor belt off and it still does it. I've jumped out the high and low pressure switches on the a/c system and it still does it. I've looked for a short in the wiring and can't find one. I don't have any check engine lights or codes. If my PCM is failing shouldn't I get a code? I have not had the a/c system checked yet. Any help would be GREATLY appreciated.
have the same problem?
