4.3 engine, 260,000 miles. Runs rough at idle. Oil pressure gage jumps all
Replaced PCV, and no obvious vacuum leaks.
Just went out an looked. Looks like I'll have to take a full day. Probably
have to pull off the fuel lines, and I'm not even sure what the wrench size
is for the two bolts.
Larger than 8 MM, smaller than 10 MM. 9 just isn't quite right. Wha'ts tht
make it, 3/8?
Anyone done one of these? What hints can you give me?
