Engine bogs at WOT
My 84 GN is in a shop and the owner is searching for a Snap On red brick so he can pull diagnostics, so I though I would try with you guys again.
I have searched the board and cannot find another reference to engine bogging down at WOT. My engine runs fine as long as I do not go WOT. I can ease up to 80-85 mph nice and smooth, but if I try WOT at any time, the engine bogs and actually seems to slow down. When I ease up on the pedal it goes back to normal. I have changed the O2 sensor and changed the MAF. Smoke test found one vacuum leak - fixed that - Problem persists. Has anyone ever had this problem and what did the problem turn out to be? |

Is the car stock?
Does it have the stock chip? Does it have the catalytic converter?

Re: Engine bogs at WOT
Is the fuel filter OK??? Maybe partially plugged... Have you put a fuel pressure gauge on and test drove to see if the pressure stays up??? Tom G.
