hi guys, my old user name here was Shaun Ladd, but anyways, here it is. My 2k auto Maxima seems very sluggish. I have an intake and have replaced the spark plugs and have a new MAF sensor. My car has 56k miles on it. Also, it seems like the fuel injectors tick relatively loud compared to the car as a whole. I can hear the fuel injectors ticking over the engine running. WHY IS THIS? Does everyones fuel injectors tick loudly? I am almost ready to drop it off at a service station for their $89.95 fuel injection system cleaning. but before I do that, can someone give me some advice??? also, I use synthetic oil. I don't really know if that matters that much in a family car though...

Thanks,
Shaun Ladd

 

anyone??? Does everyone else's injectors tick like that? With 42 views and no replies, I would hope someone could help out.

Thanks,

ticking? I doubt the fuel injectors are ticking... If you are hearing a ticking noise, it could be noisy valves or maybe a noisy timing chain.

 

injectors can tick whene they are dirty my camaro did it i had them cleand and it was fine i would try and have them cleand if you have the money.

 

do the valves require servicing on the Maxima? How often should the timing chain be checked? My car only has 56k miles on it, so I would assume both of these should be ok. And yes, fuel injectors do tick.

 

My injectors are loud as h*ll too @ around 45k(2k auto).....Must be common I guess? I have yet to hear any real valve noise, so they must be alright. And your timing Chain does not need to be checked for a long while. Peace......

 

sluggish?? what kinda gas you running in there?? these cars need at least 91 to operate properly....

 

You remove fuel injectors by just pulling them out, right?

 

i was told my fuel injectors tick, new ones are expensive.

 

I was told that my fuel injectors were ticking by the service manager when I asked about the noise. He said it was normal. He's always been pretty straight with me. No reason not to believe him. I've had no problems with power loss, tho.
