Think outside "The Box"
Car was running great one day, I went to stop and put gas in her. Tried to start it up and she barely gets enough RPM to put her in drive and move. It will start if I floor it and hold it there. To keep it running, it wont idle, so I have to gas it alot to keep the rpm up. Also when you give it gas, there is a definite bog and no response at all. Its a VG30 motor. Already had a recent tuneup 2,000 mi ago. It has been known to overheat alot. Had a new radiator installed and still did it. I'm thinking about the thermostat for that, but not my main issue. What does the running issue sound like to you all? any ideas are appreciated.
