Mass air flow (MAF) sensor/manifold absolute pressure (MAP) sensor – implausible signal with throttle position

I would make sure airfilter not blocked.

Clean the maf / make sure it plugged in.

perform the VIDA TCM test in case your throttle body is on the way out

hi
thanks for reply
have changed air filter and m.a.f sensor plus plugs and a new pipe on the m.a.p . as it only comes on when engine is switched off i wondered if there was a timer relay that could be faulty as my inner air temp fan runs for about 1 min after switching off the throttle has been upgraded to digital and the response is great at the pedal and still gives plenty of power
