Hey there guys, having issue with my 92 truck with the 3VZE. I installed new head gaskets myself, had the heads resurfaced and valve seats cut. Redid the valve clearances IAW with Haines and installed everything. Now that my truck is running, it is not doing so well. At first fire up it runs smooth, but when it drops down to idle it feels like it missing on half its cylinders. It also will not move when put in gear, since the engine cant hold the load. I have spark to all six, all my vacuum line are on right(and in good condition). I cannot find any vacuum leaks using starter fluid/ unlit propane torch. i have triple checked the timing belt to make sure it didnt slip and all the marks still line up. with the timing light on it is hitting right. Changed out fuel pressure regulator. Compression checks good. Any ideas/help would be great. Thanks guys!

Second, here's the engine mechanical troubleshooting section.

The symptom you appear to be describing, rough idling, falls under the heading poor idling. The rest is pretty self-explanatory.

Thanks MudHippy. That gave me a few more things to check on my trouble shooting adventure!
