Hey everyone, It's been quite some time since I've been on here but I have an issue with too many "possible" solutions and a very small budget. Recently my '04 GTP has been running rather hot and I have a misfire condition at WOT. I though this may be the coolant for the running hot issue and noticed my coolant was low so I topped it off with Dex-Cool and it seems to run a little better but still running hotter than it used to. And like I said I have found too many "possible" solutions for the misfire condition such as burned/plugged CAT, clogged injectors, Coils, etc. Is there anything any of you can suggest that I could try?
