Won't tell you enough to narrow down the cause, however. If suddenly, your gauge starts pulsing much more radically at idle, you'll know that one cylinder isn't firing correctly. That leaves us with a boost pressure/vacuum gauge, which can be tell-tale, if we know what to look for. But precious few of us are into racing G5 Rangers. You see these in SCCA spec race cars, like Spec Miata et. They range from about $1,000 up to a bit over $3,500. If you're really want to know the exact boost peak, actual boost, average boost exhaust oil and, water temperature etc., then spend the big bucks to buy an engine performance data-logger. If you read the fine print which came with the tool, you'd know why it is best not to use it 24/7. The pulsing is related to the number of intake strokes per revolution.Įveryone keeps bringing up the use of the Pro-Cal programmer tool, plugged into the OBDII port.
