PROBLEM WITH QG16DE!!! Advice plezzz....

Postby Madmax_GTX » October 18th, 2010, 12:23 pm

My almera has a QG16DE which i have changed the intake, throttle body plate, cams, extractors, full 2.25 exhaust. For the longest while, whenever i press instantly from stop, the rpm would build a bit and then suddenly drops as if there is some kind of power loss. The car even bugs as if to cut off!!! I have checked 3 mechanics and all diagnostics on the car is fine. I even replaced the original throttle body and cams but to no avail!! Really need some help with this one....

I had the same problem untill i changed the tps. Check your tps and adjust it if not try your injectors and spark plugs. It can also be caused by fuel starvation so check your fuel pump pressure and fuel pressure regulator
