I'm not entirely a newbie when it comes to working on car's but for the longest time I was a guy that would buy parts and hope that I'm fixing the right problem.
For the longest time that worked right up until I bought this fox body for 800 bucks that I had to put the motor in. Which came with the car but it was from a junkyard Lincoln.
Anyways
With my engine off key on I get these error codes:
23- Which tells me TP Sensor
34- Which is an EGR issue, I have no idea where I should go with that.
66- Which is MAF sensor (lovely)
and
96- Which is Fuel system related...

The problem I'm having though is as of late the car acts like its over heating and won't start unless I let it sit for a good hour or so.
It runs good but the idle does purge a bit from 700-900 RPM's
I do know that my oil pressure sending unit is out and recently my speedo stopped working but I replaced the speed sensor and the speedo-cable so I'm guessing something in the cluster broke.
Anyways any input on helping me get this car that I've fallen for back in peak performing condition is greatly appreciated. Thank you.
