Hey all,

I have an 86 Mustang GT FI, Auto.

I have a hard start, and poor running condition I cannot figure out. I put new plugs, wires, cap, rotor in it all ready. EGR seems to operate correctly. I cleaned and checked the IAC and TPS. I have vacuum to the MAP sensor. There are no cats, I found no vacuum leaks.

I cannot rev past 3,000 rpms. Fuel pressure was good, and I put in a new fuel filter.

I need some help, any suggestions?

I ran KOEO and KOER tests. I get no codes.

ignition module on the side of the distributor

That or the MAP sensor was my next guess.

Thanks!

Okay, installed a new ignition module. No better. Any other thoughts.

I did get a code 44 too.

Which if I recall may be O2 sensor related.

dlibson

No one else has any ideas?

no 44 shouldnt make you run rough.
code 44 is the egr tube has no flow.
did you replace the map sensor yet?

I read 44 as Thermactor Air system problem...

But no, no MAP sensor yet. No one had one in stock. I may try o2 sensors first. Damn first year EFI...
