im having shaking more in park then in drive,no engine light or any other signs,mechanic said he thinks it might be injecters does everyone agree,also no vacuum leaks .
I had a wicked shake in my truck when it was together... that and it was idling about 1400 rpm. I reset the idle but the shake didn't go away. My suspicion was that i had a loose plug wire, but I couldn't fire it up when I found the loose wire.. oops
nah I was at the mechanic today he double checked everything thats why hes leaning towards injecters.so I put in a chevron techron injecter cleaner to see if it would help,so who knows.I want to call junior1 but I know hes busy with tax season maybe someone else might have one thats near me.
i thought you were the one with the Ty that went to 3 different places, and the seller of your truck told it had low compression, and you went to another shop, and another....
if it's a fresh rebuild do you suppose the balance shaft is off? but honestly it sounds like a plug wire problem i had the same thing happening to my 4.3 vortec it had the serious shakes, turned out two of the plug wires were crossed. you know like th 7/4 swap on a v8. truck still ran okay and such just had a bad shake in it
