[ale_k300]

First thing guys, sorry for my english but is not my native language...

Now my problem, i got a Spyder 97 GS that has been failing a lot like the injectors were clogged... i got the check engine light, i put some cleaner on my next tank and it fixes it .... for 2 weeks, then again same thing for another 2 weeks, and now 1 week.... any idea of what can it be???

Thanks.
Alex.

Have someone at AutoZone pull the codes to see what your CE light is indicating.

Code is P0304.

CYL 4 misfire. Most likely ignition related, the ijector cleaner was most likely a fluke. Try a new set of stock type plugs gapped properly. If that doesnt help, new wires, or borrow a set from someone else that is known to be good. Let us know how that works

I've come across this on a chev, if your number 4 is at the end of your fuel rail, it may be filled with dirt. I had to remove the whole rail and blow it out. Something else to try.
