Hi Steve,
I had a similar problem on a full pressure SAAB 9000. With me it only happened under hard acceleration, and it was caused by the Waste Gate Controller being sticky and over-boosting the engine to the point where the overpressure switch came into play - this cuts out the engine till the pressure drops to a safe level again - hence the sudden loss of power. On the full pressure turbo's you get a boost gauge so you can see it happening, but I don't think the LPT's have one fitted - so its probably a garage job - otherwise Saab9000.com will show you how to test it yourself.
Regards
Hugh

Most likely I a would suspect the fuel rail had moisture in it. If you checked emissions it would most likely show no HC and alot of 02 and no CO. If it does show alot of HC then I would suspect sticking valves intermittantly . The pinging really points to no fuel issue tho. If you pull the injector connector off and no change then I would remove the fuel rail and inspect. Also make sure the wires are in the correct locations. It easy to get them wrong.

I just had the same problem with my '02 altima SE.
Took it to Buckeye Nissan in Hilliard OH. and they had to replace the two crank sensors which.
The sensors themselves were about $44.00 a piece, but w/labor about $300.00 was the total. Hope this helps.....Now if I can just get the heater working!

Do you happen to have a hacksaw blade? The thickness of the hacksaw blade is equal to the clearance of the
spark plug contacts. You can put the hacksaw blade flat
between the contacts, and make the necessary adjustment. Then, start your engine. Send in your e-mail
so we will know.
