I took my 98 Nissan Maxima to a well known oil change place (starts with V) for an oil change. One of the guys there pulled out my #4 cylinder spark plug, shows it to me and tells me that the plugs need to be changed. I told him to put it back and I'll do it myself. This really surprised me, as I didn't think the oil change places check spark plugs.
Three days later, my car hesitates when I try to start it, and shakes in Drive or Reverse. It then started to shoot out white smoke from the exhaust and I could smell raw fuel in the cabin. Minutes later, the Check Engine light comes on. I had to take the car to a mechanic, who told me that the #4 cylinder fuel injector had a bad solenoid. After the injector was replaced, the car runs fine. Any chance the injector may have been damaged when the spark plug was checked? Any advice would be appreciated. Thanks in advance!Will checking spark plug damage fuel injector?Its possible but would be unlikely unless your injectors were extremely close to the plugs and even still they would not %26quot;touch%26quot; what may have happened was that the injector (plus wires) got hit when the plug wires were removed thus causing the malfunction with the injector. This is unlikely cause your plug wires are made up of rubber for the most part and the only thing that would do that sort of damage would be a solid hit to the injector itself, possibly from the tools used to remove the plug?........Will checking spark plug damage fuel injector?Spark plugs are normally far away from the injectors. Coincidence, maybe...but I never heard of any %26quot;oil change technician%26quot; pulling plugs, especially if their 30 point check (or whatever) doesn't specify that, AND you didn't authorize it.
Without it being a problem when the car was in there, you don't really have a case, however. Remember, three days went by...Will checking spark plug damage fuel injector?just consider it dumb luck. no chance checking a plug damaged the internals of the injector. if too much gas was going into the engine which is what it sounds like, the pintle wasn't closing completely or staying open too long. most likely just bad timing on the part of the oil change guy checking it. nothing he did.checking the spark plugs will not harm the injectors. chances our that when it was removed it was probably clean off a little and reinstalled. thus causing an extra load on that particular cylinder. Or could be just that it was going bad to start with and it happend at a time, right after having the plug removed. the only damage that could possible happen is if the spark plug was removed from the cylinder head and reinstalled while the engine was warm on an aluminum head engine. dont see that happening to an injector though.
