I recently installed my 550cc injectors and took it to be tuned, however the tune isn't done. while I had the intake off I cleaned 150,000 miles of dirt out of it.

the weird things after the car is hot you push in the clutch as your coming to a stop and the rpm jumps to 1200-1500 adn then after 30 secs it comes down to normal.

Any ideas? No Codes?
