My boys 2000 Eclipse V6 has rpm fluctuation problems. But first let me give you the run down on modifications, he bought the car as is.

Modifications Engine Wise
- Apexi Rev/Speed/other Electronic Meter
- Borla Exhaust System
- Borla Headers
- Injen Air Intake System

Things to take note about
- There are two 02sensors for each header, none after the cat. converter.
- The second of the 02sensors in the front 1st header is wired to the apexi device and ecu area. Also is equiped with a 02 sensor bung hole lol sorry.
- Automatic Trans.
- OBD sensor showed no codes
- SES light is on
- No known vaccum line leaks found

Well heres the run down. When he starts the car and its in park, it runs around 800rpm; pretty normal. When shifted to drive it drops to or below 500rpm with a very rough rpm fluctuation. There was a time when he put it in reverse and it stalled out. Any advice will truly be appreciated. Thank you please hit me up via PM or txt/call 5408091465
