I'm having a minor brain lock over the CIS E3 injection with the differential
pressure regulator - my understanding was that the 5KTQ cars all came
with K-Lambda CIS injection (black fuel distributor, no diff. press.
regulator)...has your injection system been changed somehow? Did you
mean to type "1987 _4_KQ", which would make make the injecton system
correct for that car? Sorry for my confusion but troublshooting this on a
turbo vs. N/A engine is different!
