Rough Running 60

[oldgrey60]

Since new my 87 FJ60 will not run without bad low rpm stumbling if EGR is operational. Beaded air line to EGR runs great but with minor high rpm pinging? I know a non operational EGR valve will cause pinging but FJ is undrivable when operational, any help???

Correction to rough running 60

After reading a thread called "hesitation" seems I have the same issue. It's not the EGR valve but the EGR Modulator vac line that I have plugged. If the modulator vac line is unplugged FJ stumbles and hesitates at low RPM driving. What do you all think?

i had a similar problem when i first bought mine. i put in a new pcv valve and bought a used egr from landcruiser parts and it runs much better. i don't know which one fixed it but try the pcv for sure, it's cheap and easy to do.
