Ok I went out and grabbed another TPS from the junkyard. Set it between .88 and 1 OHM, it's more like between .88-90 ohms. I got the right plug for the "jumper" on the yellow wire coming off the distributor. Still runs the same. It idles great. But as soon as I try to give it any gas it pops and backfires extremely loudly. I tried adjusting the timing but that didn't do anything either so I put it back where it was. This motor ran fine two years ago, what could I be missing? Anyone know their firing order just so I can verify I have mine right?
