Idle was always steady. However yesterday after I got the suspension put back together I drove 2 miles and when I got back sitting in park just feathered the gas and noticed it wasn't responding as quickly as normal and fluctuating back to normal. Will have new wires and plugs here at 4 supposedly to put it back together. I toko my ohmmeter to all the coils to compare for fluctuations and nothing there. These plugs are a pain in the *** to get out lol.
