Hello, I pulled the plug wires one by one, no change in idle with no. 2 cylinder, could hear it sparking with wire pulled. Could it be a clogged injector? Could the fuel filer be clogged, and the bypass is letting junk into the throttle body? Any ideas on how much to fix? Thanks for all of your help, John98 corolla rough idle, no. 2 cylinder, getting spark, clogged injector?
Or it could be valves %26quot;jacked%26quot; in that cylinder.98 corolla rough idle, no. 2 cylinder, getting spark, clogged injector?
Vacuum leak? (little hose came off?)
Fouled/burned spark plug? Remove the spark plug. It's a lot cheaper and easier than an injector.
If the engine runs fine while driving, but idles like crap, it's more likely it's a vacuum leak.
Look and listen for a high pitched sucking noise.98 corolla rough idle, no. 2 cylinder, getting spark, clogged injector?
if your getting fire from the plug wire, then take the plug out and clean it, or replace it, the plug might not be firing, or theres not enough fire coming through the wire.98 corolla rough idle, no. 2 cylinder, getting spark, clogged injector?
could be a clogged injector, or the injector is not even working. that is the most probable cause because it is limited to just that one cylinder.98 corolla rough idle, no. 2 cylinder, getting spark, clogged injector?
could be a bad spark plug, could be a bad injector only two options on this.
good luck
