Yeah nice and clean.
Turn our cat has got to come out to get modulator out, so its going to stay in today. However I unhooked the line from the modulator and ran the engine to see how it would idle without the atf. Idles much better but then begins to flood. A little black smoke, so I did the clear flood routine and it was running. So I pulled fuel pump fuse, and ran it it dry and tried again. It must be pouring from the injectors because it not only turns over it cranks up and revs to about 4000 rpms.
The plugs, wires, atf must have masked this test earlier, the fuel pressure was decreasing rapidly and at the time wasnt sure if it was the fpr or check valve. Could the atf have been thrown up into the injectors and caused them to screw up? This truck was driven around for some time in this condition also sat a lot.
Anyhow, anyone got recommendations on injectors? The motorcraft ones have gold plated o-rings. Found a set of bosch on ebay for around $100. That sound about right? The red ones are stock correct?
Thanks.
