98 F150 Questions
Now that I have this in the right area, let the brain picking commence!...
Recently picked up a 98 F150, auto trans, and 4wd. Has the 4.6L Tritan V8. My questioning is even after doing a complete tune up(which it needed anyhow), when i step on the gas pedal, it acts like it's going to die, then comes back alive like nothing happened. It happens at idle. When I went to back out of the driveway yesterday morning, the truck almost choked itself. Any thoughts on the matter?
I made a recording of it at idle. https://drive.google.com/file/d/0B9p...it?usp=sharing
I've always owned 80s trucks with a carb, none of that EFI stuff so I'm new to working on vehicles with it on it. If it's normal, I'll let it be but if not, I need to know what to do to fix it as it has to tow a trailor down to TN in August.

Welcome to the new world of computer control.
98% of issues are represented by fault codes but some issues are not monitored.
Check for codes using a Scanner plugged into the data port under the dash near your right knee.
Other cause of your issue can be low fuel pressure.
Use gauge on fuel rail port to test the pressure. Should be in the 30 to 40 psi range.
Let us know how you make out.
Good luck.

There's a rubber elbow just off the bottom of the air intake that's dry rotted but doesn't leak. No other leaks then that.
Also noticed while driving it yesterday that there's no giddyup. The speedo and tach are doing what their doing so not sure if it's just my perception of things or if the rear is geared for towing.
