Hi all,
87 Berlina wagon, 103000kms on the clock, healthy motor and trans. The issue I am having is at times she starts and wont rev past 2k, when this happens the power button on the T-bar wont work and it feels like OD is out also. Other times it starts fine, runs fine but after about 20-30mins on the freeway the power cuts and I wont get any response from the throttle until the car drops below 80, or the revs drop below 2k.
Ive got a spare MAF sensor, I originally took out of the car because I thought it was the issue I was having, but that turned out to be the fuel lines inside the tank being stuffed.
I'm tossing up if its worth getting a new MAF if possible or trying to diagnose the issue, any suggestions would be a big help.
Thanks
