I would check your coolant temp sensor first. When you hold it at WOT its in clear flood mode. It is fuel injected correct?

Check for a vaccum leak around the throttle body area! In 90 it should be still TB injection no?
Verify correct fuel pressure, timing etc!

it is fuel injected
timing is good and compression
put in new plugs and 5 and 7 plug wires seemed crossed
