Hello.

Within the last 100 miles, has been experiencing a problem while driving, and it is getting progressively worse.

The vehicle idles w/out any problems, but under load it experiences dramatic, intermittent power loss. It happens at all speeds, in all gears, and at hot or cold engine temperatures. I’ll be driving along and all of a sudden there is no response to pressing on the accelerator. This will last from 10 seconds to 2 or 3 minutes, then every thing will return to normal for 5, or so minutes, before it recurs. The engine does not stall out, and if I pull over to the side of the road, the engine will idle, as normal.

Within the last 3K miles I have: changed oil, rotor, cap, plugs & wires, t-belt, air filter, air box thermostat, flame trap element, and air filter. Have also replaced the external fuel filter and in-tank fuel pump, cleaned the throttle body/valve, replace the gasket and replaced the bellows tube going into the throttle body.

My first thought was that it was a bad AMM, so I changed it out with a known good AMM, but the problem persists. I gave a cursory look at the vacuum hoses, and they look ok.

What is going to be my next move?

Thanks,

Ally
