So yea, i've had my '89 S13 coupe for a while now (got it January of this year) and have some various ups and downs. First the stock speakers were 'terrible' and got those replaced with some nifty pioneers (yea, I know there are probably better companies, but I just got a thing for pioneer
). My clutch also went out about a month after getting the car (car came with 110k miles, so I wasn't terribly suprised by this, but was still a drag =\). Whats been the weirdest thing though, has been my odd experiences with my fuel injectors...It started about 2 months into getting my S13 when one day while driving down the road my 'check engine' light went on. I was pretty much like 'damn, what now? -_-' cause I just replaced the clutch that weak so brought it to the shop and they said it was a leaky fuel injector. Well, before buying my s13, I pretty much read the entire faq here at 240sx.org so I'd heard about other owners having injector leak issues around my mileage. What I wasn't counting on was my mechanic telling me it'd be around 400-500 bucks to replace all my injectors O_o.
Now here's where my story gets kinda weird. Now I pretty much didn't have the money to go replacing 4 injectors so I pretty much had to drive on some pretty crappy mileage for a week or two (we're talking about 220 miles to the tank -_-). Well, eventually time came for my sheduled oil change and I decided to bring it to a local Jiffy Lube on sorta a spur of the moment thing. Well, I was out there for a little while (not too long though, hey, the're 'jiffy' for a reason ^_^) when one of the guys on duty told me that the whole fuel system was pretty dirty and the recommended an engine flush. It'd cost me an extra 20 bucks, but I was like, what the hey, my cars already kinda messed, maybe it'd help. ^_^ Well, let me tell you, after they were done and I started up my car, the engine light was off and my car was soaring! I filled up right after the oil change and I pulled 360 miles on that tank . ^_^. So yea, was pretty happy for awhile...
But then, gradually, after the next few fillups, my mileage gradually got worse. 340, 310, 280, and right after my next oil change, that dreaded light came back on -_-. So basically for the last few weeks i've been experiencing some weird occurences. After I stalled once leaving a friends house (he lives on a hill, yea, go ahead and laugh. It was embarrasing after driving manual for more than 1/2 a year -_-) and by the time I got home the light went back off O_o. Then a few days ago after leaving work, light comes back on and i'm like 'S#@#$%!". Then when I wake up the next morning, suprise, lights off again O_o. So now i'm not all that sure what to think. I mean, I guess it could be a faulty sensor, but then again my mileage has been kinda crappy lately. I have been having to pump some A/C lately too, though, so that could explain my less than stellar mileage. I guess what it all comes down to is this. As a fairly inexperienced car guy, how can I tell if I have a fairly minor problem of a sealant leak on my injectors or a more dire one, requiring a full replacement of all my injectors? O_o. Is there anything I can maybe see visibly under the hood that might help in determining if I really need 'all' my injectors replaced? (I mean, what if its just one thats leaking? I'd think it'd be kinda a waste replacing them all then =\). Finally, if its the seal or the injectors themselves, how hard would it be for me to attempt to just try replacing them myself or would bringing it to a shop be the best option for me? Well, thanks for reading through all this junk, i'm sure it hasn't been very interesting O_o. Any help is appreciated, thanks!
