Hey Ladies and Gents.

First let me say im no mechanic but im learning.
Second this is my first truck ever.
third hellllp....

I have recently purchased a 1993 F150 4x4 with 123,056 miles. (Sharp Lookin Truck)
I bought it for 2800.00
5.0l 302 EFI
31" tires, diamond toolbox and ect.

I got True duals... i dont know if should be happy or not lol.


My currently known Problems are:
Im puffin a lil black smoke out my pipes and I know this means im running rich.
So i checked it out...
Upon further inspection i find that i have long pipe headers and no cats. And they are 2 seperate lines no y, no x pipe just straight back never meeting.
I have know idea what kind of mufflers i got but they r loud and sound awesome.

It seems a few things have been disconnected to assist the engine and other systems i guess. due to having only one O2 sensor.

One thing i know is the belt system no longer runs the air pump its bypassed or should i say the belt doesnt run around it.

And some pipe that goes to some vac system, the end of the pipe is clamped shut .

The truck runs really really good like a champ but it idles a lil rough at stop lights or in park and it runs rich.
i know some of the problems aredue to the fact i have only 1 o2 sensor.

Any ideas on a fix for this?

I have purchased a code reader and i hope it will clue me in to the idol problem and the black smoke.

I hope to have some pics to post of it next time to make things easier.

Later All and thanks.

 

check the timing, do a code scan, and if you got any exhaust leaks before the 02 sensor fix them
