(Archive: GFC - by johnyrottin, started: 04-15-2009, last post: 2012-01-11 10:05:04 CET)
This is my continuing saga of learning for 4.9 liter owners that have yet to encounter the problems and people considering the swap. Recently, I experienced a complete loss of “punch” power from the motor. I replaced every electronic item between the distributor and the spark plugs with no...

(Archive: TD&Q - by fierobear, started: 03-29-2006, last post: 2006-08-11 13:06:44 CEST)
I've just about given up on my 3.4 Formula. I've had a lot of electrical problems with this car, the latest being a fuel pump relay that I can't get running, a smoked ECM, and an EGR solenoid that I can't make work, which means it can't pass smog (which is due this month). I'd been thinking that...

Caddy 4.9 in Triumph Stag / Font of all 4.9 wisdom
(Archive: TD&Q - by Will, started: 05-30-2002, last post: 2002-11-04 12:03:03 CET)
Perhaps this should be in O/T, but it is technical and (I hope) will contain information which can be applied to Fiero conversions with this engine.I am convincing myself to buy a '73 Triumph Stag desperately in need of restoration. Since it currently has no engine or transmission, and the stock...
