Replying to: fws4 (Jul 13, 2009 11:12 am) Sounds like it got too hot and blew a head gasket. Quick check is to fill cooling system so it is full. With radiator cap off and water to the very top crank the engine over. If water comes flowing out you have combustion gas in your coolong system and either a cracked block or blown head gasket. OOOps!

Replying to: hopkins7 (Aug 25, 2008 6:49 pm) There is a service bulletin about loose hood hinge bolts causing a clunk. Replies to this message: hopkins7 (Jul 28, 2009 6:50 pm)

Replying to: mickeymouse2 (Aug 26, 2008 7:20 am) mickeymouse, thanks for your help. I finally got around to checking out Technical Bulletin 01-08-63-001B through a friend. The cause of my noise was the Hood Hinge on the right side - excessive clearance. Had to install a spring washer. Problem solved.

#349 of 364 02 s-10 Xtreme 4.3l cylender 4 misfire code P0304 by giakamo Jul 31, 2009 (5:26 pm)
I am new here ad will try to get to the point. i bought my truck new in 02 and it has only 40k miles on it. my battery died, replaced it with a new one, i am now getting P0304 cylinder 4 misfire ses light is on and idles rough over 30MPH and it flashes. I have replaced spark plugs, to no avail. I then looked at the cap and rotor and they were corroded so I replaced them. ( i thought that would fix it honestly)and I still have the misfire in cylinder 4. very rough idle, stuttering when driving from a stop. once at 50MPH it's smooth as silk. I have put fuel injector cleaner in the gas tank as a preventive measure after this prob started just in case. I am going to try changing out the wires next. anyone have any ideas on this? After the wires, I will have spent 260 dollars on this problem.

Replying to: giakamo (Jul 31, 2009 5:26 pm) Can't help you with a 4.3, don't know much about them. I do know if you keep driving with the check engine flashing, it will ruin the cat converter. Replies to this message: giakamo (Aug 01, 2009 8:47 am) giakamo (Aug 01, 2009 12:46 pm)

Replying to: gonogo (Aug 01, 2009 8:13 am) No worries there.. i am not driving it at all.. i baby this thing and don't drive a whole lot... ( i have agoraphobia and require meds to just leave the house) warranty ran out in april.. and just want this fix as cheaply as possible. if it's not the wires, then i can't imagine anything else but the fuel system... I am still open to ideas as i haven't had the chance to get to autozone for the wires Replies to this message: giakamo (Aug 01, 2009 12:46 pm)
