Hey gang, I've got a 2.5T2 Mitsu with Boostbutton SMEC in my Dakota, lately it's been running odd. It starts and runs fine but maintaining speed it feels like the ignition cuts partially out. It will rev and boost but it feels flat, and then suddenly it will surge and run peppy before there's any boost. Kind of like if you road a dirtbike down a hill and kill the ignition with it in gear, it rolls at the same speed and if you open the throttle it sounds like its accellerating.... turn on the ign and it surges up to speed.
I'm wondering if I've an electrical gremlin with a weak ground causing this. Because since this started my turn signal causes the temp gauge to pulse in time with the blinker. Charging system shows weird too, gauge says it's closer to L than H but a vom shows 15.54 or better.
Engine doesn't die, it will accelerate just not the peppy rev I've been used to the last 10k
Any ideas?
Thanks
