88 Suburban wont idle. Going down the highway, let off the throttle and it died. Timing was off and warped some intake valves. (found while trouble shooting.) Replaced all pistons, all intake valves, TPS, AIC, MAP, EGR, egr solenoid, coil, pick up coil, ignition control module, plugs and wires. Checked for vac leaks, checked fuel pressure (13#) I think that is good for this TBI. Rebuilt fuel regulator and TBI gaskets. Injectors seem ok, good spray. As you can see tons of money already. Any ideas?
