| lots of stuff in under 'Pages" tab above. No need to apologize. Important issues to do with your 90 is to first get up on the maintenance. Here are some issues: Check for ECU codes and operation of the O2 sensors. What is mileage and when was the timing belt replaced? Probably should do the 120K maintenance on the belt. There is a complete discription in the Tech tab under 'Pages'. Use only OEM parts here. As far as connectors these cars are very sensitive to contact at these locations and connectors are prone to corrosion so I suggest you check and clean as many as you can get to. You note that the injectors connections will be replaced. When they are disconnected Ohm the injectors (digital meter only) they should be 10 - 14 Ohms and close to lower reading when cold (new usually ohm 11.5 at 75F). Use dielectric grease in all connectors. Your car has the old style pintle type injectors
that are prone to failure. If they ohm out of spec they are on their way out and you should look into upgrade to new style. If that is the case there is much info here on that so get back to us. Especially check the coolant temp sensor connector and the sensor. Lots of runability issues here if bad or corroded. Check all grounds and add a ground net system cheap to do like < $10. See 'Pages' Clean batt terminals and add dielectric grease to cables and posts. Clean the throttle bodies with cat and sensor safe cleaner. Replace the PCV and hoses with OEM parts. Later
