Hi y'all
I've been experiencing flat spots at 2000-2500rpm and 4500-5000rpm.
Today I had the car read and it threw up the following fault codes:
P0100 mass or volume air flow circuit malfunction - intermittent.
P0101 mass or volume air flow circuit range/performance problem - intermittent.
P0299 turbo/supercharger underboost - intermittent.
The MAF amps were tested and were fine, but am I right to assume this still doesn't mean the MAF is okay.
The grams per second on idle was 4 and as it began to increase under load, at 2000rpm crashed down to virtually nothing.
I'm heading to R Tech on Wednesday and don't want to go there with any issues and be turned away. Especially as it's a 500 mile round trip.
