I am helping my neighbor with his 98 tacoma 4wd with a 2.7l 4cl.
It originally had a dtc code on it. I fixed the ETC and the 02 sensor, and code is now gone.
However it still misses/rough idles, and rumbles at higher speeds.
I checked the plugs,wires,coils,fuel injectors,maf, and none of them had any issues.
We also smoked checked the entire vehicle and no leaks.
The truck was taken into a shop for a blown head gasket before i bought it. They fixed it but am not 100% sure of there work.
My friend said the next thing he recommends is check timing.
Is there any other known issues that could cause this? There is no CEL or Pending codes on it anymore.
Thanks Guys.
