Hello,
I recently got a '92 FJ80 and have been working out the kinks to get to run better. The truck was bought with a broken ignition cable for the 6th cylinder. I have replaced spark plugs, cables, distributor cap and rotor. The engine was still idling rough and at low RPM after that so I was recommended that I gap the plugs. (I thought they came gapped.) I gapped the plugs today and most of the rough, low idle was gone. Truck was idling quite well and felt more powerful.
I then went to get the battery tested and it was shot. I went to Walmart and got one. After installation, the engine takes just as long to start up as with the old battery and the rough, low idle is back.
Does anyone have any suggestions? I don't understand how changing the battery could mess with the low idling.
Thank you!
