Has No Power

[Phatt_daddy]

Ok so I've finally gotten my son's 00 out bask together and on the first drive... it had some decent power. Fast forward a week when I took it out again... the car had no power and would not pull a small hill. No...i have not put a tinder on it. Yes I have deleted the egr. Yes I have deleted all cats. No I do not have MIL eliminators. Yes I have 2.5" Magnaflow exhaust. Engine I put in it had less than 100k as did the trans. Any ideas on where I should start looking

First are you certain about the motor's basic health? Engine compression and/or leak down?

Are you sure about the health of the alternator and charging system? Here's some information that may help.

Do you have an ODB2 scanner that can read operational data?

If not here's some information on an affordable windows based unit.

With an ODB2 scanner you would be able to answer (rule in/out) questions such as:

• What is the fuel pressure as reported by the FRPS
• What is the EGR as reported by the DPFE
• What cylinders are misfiring
• What are the long term fuel trim (LTFT) values are are they changing with RPM's
• What is the engine temperature? Note, the PCM will pull timing IF it "thinks" that the motor is over heating.

I might begin by putting all the stuff back in that the car was designed to have.

I'm certain that you've ruined exhaust scavenging and now the EEC is probably reverting to 'limp mode' because of hacked modifications.

Your list of codes should be significant.
