hey i believe im having a problem with my rtek ecu.i was wondering if theres anyway to test the ecu to see if theres a problem...like with a voltmeter.

i have a light tester that checks for engine error codes. if there is a problem with the ecu would i get a code from that light tester?

my other post about the problem im having. https://www.rx7club.com/2nd-generation-specific-1986-1992-17/starts-runs-shuts-off-no-idle-no-codes-796646/
