Is this a Throttle Body Injection (looks like a Carburetor with two injectors inside) OR is this Multiport Injection (No Carburetor and you see an Injector at each Cylinder)????
You may need to invest in a Repair Manual. Haynes is OK, Auto-Zone sell them for about $15. I not say it the best, but, if you mechanically inclined I think it be all you need.
