SUCCINT. CLEAR. PERFECT. THANK YOU BROTHER.
97 towncar. I keep getting P0352 … I switched quad coil, the wires, the spark plugs. still following that cylinder regardless of what I do. How do I test the connector that goes into the quad pack?
Just got done doing a head gasket job on my 2zr-fe. Now got a misfire issue, replaced spark plugs and now coil in 1. But the misfire then jumped to 4! So put another new one into 4 and now it’s back to 1! Insane. Did the whole switch around before with the coils and it kept jumping so that’s why I replaced the coils. I’m guessing it is pcm now. Not sure. Did check wiring and the readings were normal. Thanks!
Replaced the coil pack, wiring and spark plugs on a 96 ranger. still no spark on cylinder 3. Any ideas what this is?
I would test the wiring.
2004 rav4 awd M/T
P0302
new spark plugs-ngk’s
new coil packs-oem denso
Checked the ohm output on injectors-all match
Swapped injector to different cylinder-same result p0302 still remains.
I took an old coil pack unplugged #2 to plug in old coil to hold against engine to see spark- there was spark… lol what else?
Anything I say is a guess, but I would check the wiring harness for a bad connection that is causing an intermittent problem.
