rough cold start

[muhl5443]

i have a '98 exploder w/ the V6 4.0L SOHC ever since it has gotten cold here which was about mid nov. my truck has the hardest time starting. i once got codes that all of my cylinders were miss firing and that both my 02 sensors were running lean. whatever the problem is it is eating up a lot of gas. i use to get 400 per tank now i only get 200 per tank. any ideas?

I'm hunting down a similar problem. I did find this.

Not sure if that's what I'm after yet or not.

Try cleaning your MAF meter to start. Change Fuel Filter. Basic tune up if not done. Maybe do a Seafoam Cleaning. Chances are its deeper then that, but its a start. Could likely be a bad Intake manifold Gasket common to go bad on SOHC explorers.

it was the upper and lower intake mainfold gaskets.

I'm doing mine in the morning. I can't wait until it starts nicely in the morning again!
