As I continue to fight my P0304 problem. I came across other threads with similar problem. Seems like my options are using seafoam, some kine of fuel injector cleaner (going to try lucas fuel treatment), valve adjustment, and replace the injector.

I figure i'll start off with the cheapest route first. I've been checking around but can't seem to find either seafoam or lucas fuel treatment locally... I am down at SJ/Santa Clara area.

 

Kragen's has Seafoam and I think they might have the Lucas

 

I can buy Lucas products at any Kragen between Fairfield and Sacramento, so it should be easy for you to find locally.

Not sure about the Sea Foam, but I've never actively looked for it, so I'l believe what tanz1983 has to say.

 

Yeah, Seafoam is worth it. I use it before every oil change.

 

seafoam gave me worse mpg and their customer support is complete ****. I suggest avoiding seafoam

 

really? what was your method of application? and was your MPG permanent?

 

I'll try a different kragen and see if I have better luck. thanks guys!

 

i applied seafoam to my 1990 toyota truck.

3/4 went into gas tank. 1/4 went into crankcase.

next gas tank went up A LOT for mileage... but next gas tank, it returned back to normal...

 

leo, autozone. I haven't had much luck with kragen.

 

thanks bro! there is one on my way home... i'll give that a try... Do I need to have it with full tank of gas? or is it okay to drive around with it with only 2-3 gallons in the tank (more concentrated)?

 

Call this pepboys and they have it!

autozone has them both.. I use the Lucas Octane booster about once a month.. I like the results

 

Thanks, I picked up Sea Foam at Pepboys. They had Lucas as well, but I wanted to use Sea Foam first and see...

I injected ~4oz of Sea Foam through the PCV while engine on and ~.33oz after I turned the engine off and let it sit for ~5 minutes. I then put the rest of the 11+ oz of Sea Foam into the gas tank with ~6 gallon of 91 octane.

I also changed the PCV since it's so cheap... But DAMN!! Look at this sucker (old, new, old, new)! the old one is not stuck or anything, but might not 'move' as well due to all the crap on it...

It's driving VERY smooth right now but we'll see how it goes tomorrow morning...
