First off i start the car it sets for maybe 45- 1 minute then its like a switch turns the engine to shake mode and goes away after like minute and a half. nothing performance to the engine. i have atune but it did it before the tune aswell. i have no catylitic converters which the tune should turn the rear 02 sensors off. I dont know where to start to look. i checked the plugs. they are a little rich. And When it does the shake thing it has a very strong gas smell. worse than the usual no cat smell

 

Might want to start out by making sure the rear 02 sensors are turned off and also have your tune checked on the dyno to verify your spark, timing and air/fuel curves are all within optimal specs..

 

Have you data logged during the event? I would look at fuel trims and see what they are doing.

 

Hows it going?

 

I don't think we'll ever know Glenn. Like the F-150 forum I'm on we have here a lot of new one question members that never comeback to say thank you, kiss my a$$, or anything. For me, my vast knowledge isn't just put out there to go without any consideration.

 

Just goes to show how inconsiderate some people can be, especially if they aren't provided with the answers their looking for lol.
