Mazda preacy speort, petrol losing fuel and jerking
 

I have a mazda premacy sport, 2ltr petrol, which
Is using a lot if petrol.

The car jerks she. Start to move, the gear stick also shakes, until I build up speed. The rev counter goes above 1500 when turning the engine on

I we told it could be the maf sensor, and to unplugg it, when engine is running. I was then advised if the engine continued to run (which it did), then it's a bad sensor??

Recently it's had a new fuel filter, New plugs, it has 90,000 on the clock

Could be a bad MAF, could be a bad ignition coil, could be split intake hose.

Is it correct, when you disconnect the maf ,and the engine continues to run, which it did , that sensor is bad??

Previously had a code to replace solenoid valve, I have replaced thy, and the fuel filter. Another code has popped up0102??
