Have a stock 86 mclaren capri 5spd
Just went through everything on my 88 cougar no start it was the computer.

It starts goes to 2k rpm for 5 seconds then dies
If I try to rev it it breaks up and won’t go past 2k
I had a good tfi module and iac from cougar and put a new map sensor in too
Put new fuel filter and the pump is working
Ran scanner came 67 o c
No idea what is wrong
