Thread: 2005 GTP engine power loss (No codes and no errors on the DIC)

Seeing if anyone has any idea before I give up and sell my car, was up for sale then decided to keep it now its having a random power loss so I want to get rid of it if I cant figure it out.

This is a very, very intermediate problem, my car will have a huge power loss until I shut my car off and restart it, I can shut it off for one second and start it then its back to normal. Its been doing this about once a week

Also once in awhile if I use the remote start, it will start then stall, I then try it again then in will start and stall once again, or it will keeping cranking till it starts(then have to start it with the key since it only allows two attempts before its disabled), but it never has a problem starting with the key only remote start



there's 0 pending codes, 0 history codes and 0 present codes

here's what im guessing it could be

1. Throttle body
2. PCM
3. EGR valve
4. clogged cat (but shouldn't it do it all the time)
5. fuel filter (but was told 05 doesn't have a external filter, been too lazy to check if it does or not)

any input will be appreciated thanks in advance

05' doesn't have an external filter.

I would check for vacuum leaks, I just bought an 05' and had huge issues with the car running great then it would just lay over, it also go to the point where I started getting a P0068 and I found that the vacuum lines that run from under the snout to to the MAP on the firewall side and the boost solenoid on the radiator side were all in bad shape. I got the car running a lot better now, but I still have an issue.
