1979-1993 & 94 Conv
I'm rescuing a 94 900 CE with 129,000 mi and it's got me stumped. The car runs, but only 1 & 4 are firing. 120lb compression across all four cylinders. Fuel injectors and plugs are known to be good because they came from a SAAB that ran well, plus voltage is correct when running. There is spark at the cap and at the plug. The ole' carb cleaner spray test fails to detect an intake leak. No check engine light. Tested a known-good ECU and no change.
What's your suggestion?
