Karen was re-united with her own car at a recent shakedown session at Keevil airfield. The morning was very wet and immediately the car was running roughly and within a few laps of the circuit layout a Check Engine Light (CEL) was showing. This was quickly diagnosed as a problem with the Mass Airflow Sensor (MAF). The air-filter had become sodden and water was getting onto the MAF element causing the car to run roughly and go into limp home mode.
TenguDo Motorsport mechanic Mike installed some tubing to prevent water ingress into the induction system. However, this was still allowing in water, as the circuit was just so wet. A quick re-think saw the tubing within the engine bay. This meant hot air was being breathed in, but at least it was dry!
This saw the car running perfectly and Karen was extremely happy. After lunch things began to dry up and Karen got some decent running in her own car for a change. Power was good and torque was strong. Everyone was enthused and the plan was to enter the upcoming Silverstone races upon the return home.
Having returned home, it soon became apparent that when trying to remove the car from the trailer it wouldn't start. We feared the cambelt had slipped again! Various checks were performed but it all pointed to the timing. Mike came to the rescue again on the following weekend and proved the cambelt was fine. The brand new crank sensor was replaced with a 2nd hand item and the car started without trouble. After less than a day of running the new part had failed, which was very surprising, especially as it had no moving parts and was just a glorified magnet!
Following this, a Silverstone entry was duly sent. Richard then spent some time on the Sunday fitting a larger bonnet scoop and an intercooler spray system. Here's hoping these improvements help Karen get the best out of the car at Silverstone and she enjoys a couple of trouble free races -It's about time!
