Well I finally found my Thunderbird. Its only take two years. So its a '94 4.6L and I have a problem. Its running rich and running rough. When you stop it dies. But if its out of gear it'll idle. I was told by the PO that it was the DPFE sensor. So I picked one up from Autozoo. I was looking for the vacuum tee at the back of the intake to see if it was cracked. I have some other things to check as I just brought it home like 20 min. ago. Also are the '94 4.6L OBDI Or OBDII? I don't have my manual yet so just thought it would help. I thought maybe you guys would have some other things I could check. Thanks for the help, gotta finish making dinner.
