I gotta 90 coupe Sohc ka24-e

It passes the 25 mph test but once he try's the 35 mph
Test while staying there for like 5 secs power drops out
Then kicks back in wont stay steady. When it does that it
Cancels the test took it to 2 different shops did this 6 times total

Replaced:
Fuel pump
Tps
All rubber fuel lines
Cleaned egr
All new vaccume lines
Newer injectors an pigtails
Still made 113 hp on the dyno but the wide band
Said it ran way lean when it cut out cant think of anything else

Car idles perfect when it cuts out u either get off the gas or go
Faster then it drives good
