| Skratch,
The same thing happened to me but from 3rd to 2nd gear. The car was running on 3 cylinders but when I shut it off and start it back again the idle was very smooth, however, it did set a fault in the DME and the dealer found out because I had a check engine light due to bad O2 sensors and voided my entire drivetrain warranty.
Compression and leakdown tests pass before I installed the turbo kit. |
