X-90 engine bogging under acceleration

[Ken H]

Thanks for your reply Fixkick,

2 door coupe

Switched the MAF from my other 96 X-90 (yeah I own two of the 7,000 built) to see if that solved the problem. Same result no improvement.
What numbers should I be looking for from the MAF.

I will check fuel pressure Over the weekend. Pretty sure the FPreg is not working properly. Pulled the vacuum hose off and applied 15lbs of vacuumed with a vacuum pump and the fuel pressure at idle only drop from 40 to 38. Leak down test passes.

Not in Denver. Coastal Virginia.

Removed both rear tail lights, no ground wire. I will have to hunt that down. Maybe someone else knows it location.

I have also noticed at start up I no long get a idle up. I starts fine but idle is around 800-900. On my Tracker and the other X-90 I see high teens until engine warms.

Thanks again for you help.
