OK guys I have a 2003 svf with 105k miles. Mods are intake and ORP. Timing belt never changed. So here is the problem. Car will start fine until it warms up then it will start to miss,but not bad. If you drive the car the missing will go away after awhile but come back. Also car will rev to 2-3k on its own until at a complete stop.but it won't rev all the time. No cel or anything. I pulled the codes and got p173 fixed it and it still says I have it. Also got codes p200 p300 and p400. Could this all be from timing belt? I changed plugs and cleaned throttle body really good no help, so I also cleaned maff.

Yeah I did try resetting the battery. Same codes. Also alternator wire do all that?? And I threw a egr code but I dont have a egr? Lol this car has a mind of its own. So check for what bad connection or wire showing? I feel that is not the problem here.

Yeah, don't like those code numbers, they're all generic ones not specific & the last (400) is for a system not on the SVT.

200 is an injector code, but it isn't pointing at a specific problem & 300 is the misfire code that would go with that.

Don't want to trust them as the info. is limited & at least some is wrong.
