Ok my girlfriends car is having an issue, she said she was just at a light
and then all of a sudden the motor started shaking and the car ran poorly.
So went and did some diagnostics, pulled each spark plug wire, pull one of 3
of them and it would die out on you, pull the plug for the far driver side
cylinder, didn't seem to effect it that much, hmm, was getting spark ok on
every wire. So I went and pulled the clips on the injectors and tried
unplugging them one at a time, get to the far driver side, unplug it, no
effect, didnt run any worse, so I'm 99% sure its the injector, it seems to
be really loud, so I think its just clogged up, dumped some injector cleaner
into the tank and had her drive home, only about 6 miles so I'm sure it
didn't get enough cleaner to clear it. She says it seems to drive better
when she's driving, but stopped it seems to run rough. Maybe under throttle
its opening up enough to deliver enough fuel to the cylinder to smooth
My big question is, does Hyundai cover fuel injectors under the 10 year
100,000 mile warranty? or does it fall into their grey area.
If I need to change this myself, do I just need to relieve fuel pressure,
and then does the rail move up enough that I can slide the feeder hose off
the injector and then pull it up and out without much problem? I work at a
chevy dealership so I can get the new injector pretty cheap.
