I have a 97 F150, 4.6L, with 94Kmiles. Changed the spark plugs a few weeks ago. I am having a problem with the engine bogging down when I give it the gas. I start it up and let it warm up a bit and it will dog right down. Drive a few miles down the road and will not have the problem anymore. Any ideas? Thanks for the help,

Greg

 

Have you had it scanned for codes yet?

 

Yes, the code came up for running rich/running lean. Any ideas?

Thanks

 

Try cleaning the MAF and changing the fuel filter.
