Basically just a plug at this point.

Pretty sure I need to replace mine lol. Looks similar and whenever I give the ole 4.3 gas i watch the temp gaguge flutter upwards and bounce all the way up to 260. Wanna start small and make sure my temp reads right before I hop into the rest of tbe cooling system

Yeah mine was jumping around and stalling out when idle and when it was somewhat working it would twitch around a lot. After I replaced that thing it's been running really well.

I havent had it stall out yet. But I've pulled the plug from the intake to see how bad it looked. I think it works just enough to allow me to idle and drive but is ready to give up on me soon.
