1998 4runner SR5, 135,000 miles.
Recent tune up, plugs, wires, boots, fuel and air filter, run several bottles of techron through the fuel system, cleaned tb, and maf. Flushed coolant and changed t-stat. Timing belt and water pump and belts were changed at 115,000.
No stored codes or cel. Checked vacuum hoses with visual and starting fluid, pcv valve seems to be fine.
Runs really sluggish when cold, i.e. first thing in the morning. Stumbles really badly trying to accelerate, no power. It does run better when warmed up, but still has a very slight miss.
Any ideas? I am kind of stumped at the moment.
Thanks in advance
