96 Taco 3.4 auto random engine skip or buck.
Annoying and unreliable.Cant figure this 1 out.So heres a list of new parts replaced to try and resolve this.CKP,FP,MAF,CMP,TB and WP just cause I was in there.This is not a misfire.PC cuts fuel to ALL cyl at once.Verified with noid lights.I have 2 codes that are irrelevantO 340 & PO 401.Engine runs great and has power otherwise.This problem happens any time the engine is running.
Thanks Bigblock

Its getting worse.Wont idle anymore.Heres a list of whats been done today.Plugs,wires,coil boots,O2 sensor(front),CTS,TPS,cleaned throttle body.Really all thats left is the ECM and wiring harness.I'm not sure a dealer could find this problem.Any thoughts?

I finally found the problem.For those of you who were curious about this the cam position sensor wires were crossed.I guess the last village idiot had to replace the connector.
