Running Rich?

[jrp27540]

I bought an 88 LX 5.0 a few weeks ago. I had a feeling the car was running rich due to the smell from the exhaust. I changed the oil in it last night and the oil smelled of gas. The mods that I have been able to identify at this point are as follows:

• MAF conversion
• Cold air intake
• Bigger upper and lower intake
• Bigger fuel injectors
• Bigger fuel pump
• MSD ignition
• e303 cam
• headers

I am used to the 4.6 mustang, but am very very new to the 5.0 fox body. I have been doing some research on this and sounds like it could be a number of things based on the mods done to the car today. I do not see a "check engine" light on, so im not sure if that means the car isnt throwing any codes or not.

At this point, I am looking for any direction that I should start looking at first and work my way down the list. It sounds like I have a large learning curve in front of me with a car that is far from stock... Any nudge in the right direction would be appreciated. I dont want to drive the car until I get this figured out...as im concerned about how much damage has been done to the internals from the previous owner.

Thanks for any information!

The 86-88 year cars don't have a working check engine light.

Dump codes sticky.
Look at the top of the 5.0 Tech forum where the sticky threads are posted. One of them is how to dump the computer codes. http://www.stangnet.com/mustang-for...codes-from-eec4-in-86-95-5-0-mustangs.889006/ I highly suggest that you read it and follow the instructions to dump the codes.
