I have run into another problem that I'm trying to fix on my 92' pickup 3.0L. After the truck is warmed up when I come to a stop light it will have a quick shake. Almost like a jolt. If you sit at the stop light for an even longer period of time it will get worse and repeat itself.
I recently changed the fuel filter, air filter, spark plugs, spark plug wires, distributor cap and rotor, o2 sensor, pcv valve and timing belt. I also checked the throttle body it's pretty clean. After changing all these I seem to have gained alot of lost power while driving. The problem just shows up while I'm at a stop in drive. Let me know what your guys' input is please.
Thanks

Has the Truck ever had the head gasket replaced that you know of????

Sounds like the beginning of symptoms of when the head gasket went out in my 93 Runner.

 

I called toyota corp about a month ago and gave them my vin number. They told me that the headgasket recall has already been done. The only problem is that no one in my family ever recalls taking it in to get the recall done. (The truck has been passed from family member to family member)
Would I be losing coolant if the head gasket was bad?

 

loss of coolant is one sign..........have you noticed any mixing of fluids (oil in water/water in oil, etc.) ??

 

Also, did you connect all your vacuum lines?? and correctly so???

Also, re-check all your plug and distributor cap wires
