I think that you should do a compression test, to make sure there's nothing more serious going on first. If compression is OK, move the spark plug and coil from the misfiring cylinder to another cylinder and see if that "moves" the miss to that cylinder. If it does, you have a bad coil or plug. If it doesn't, carefully inspect for broken wiring. if it's not too difficult, move that injector to another cylinder to make sure whether its the cause or not. Cleaning the injectors may or may not fix them.
I ran it like that for a very long time then I just put in a used motor from Japan didn't want to go ahead and fix the compression that was off on cylinder number 2 should have done that a long time ago cost me about a thousand for the motorh500 andput in
holy heck! new motor.. my element for two years with do this every day. start up. if I do not let it run for ten minutes to let it warm up then it will stall anywhere between 5 - 10 times every time I come to a stop. if its warmed up it works perfect.. does that sound similar
cold didn't help when i was in northern states but it did not stall just ran rough at stops and idle. I actually had to start putting it in neutral at stops. Whats the computer reading??
I'm dealing with same issue of rough idle and stalling 2600 element. I just got code PO when 72 witches a rich fuel mixture. I have replaced the PCV valve,I clean the throttle body, Installed new map sensor, Replaced both oxygen sensors on the exhaust, Changed the plugs, replaced 1st cylinder coil, Have checked for vacuum leaks.
I have changed every valve and sensor including throttle body also! Even put in new catalytic converter and exhaust muffler and resonator. I am about to go out and check purge valve.
