so ive cleaned my iac, new plugs, wires, and injectors. I dont have a compression guage so i havent performed that test...
It comes and goes. I can pretty much unplug the battery for a few minutes, all is normal. Basically i can get it to act up when im getting on the freeway. 4500 rpm or so shifts and most times coming into 5th gear, and i get off the throttle... it starts shuddering and the CEL comes on flashing. I can pull to the side of the road and unplug #4 cyl wire. No change, and the spark jumps to the manifold. reconnect it, and unplug the injector... no change. I run a volt meter to it... and nuthin.
However, driving through town nothing happens. Its all gravy and cool. Just running revs beyond mid range (2500-4000 rpms) for any length of time she starts to give out. Any ideas?
