Icon9 Sluggish Prelude

So about 3 months ago my prelude began acting up after i had used fuel injector cleaner. The only reason i used the cleaner was becuase it was free from like autozone with a purchase. I have absolutely no clue if this correlates at all but a day later my car began to stall at high rpms and most noticeably at around 4000 rpms in 4th gear. Sure enough it wasnt long before it began throwing engine codes which i checked and turned out to be a 2 and 3 cylinder missfire code. I considered a few things such as clogged cat but it went away by itself before i could really have it checked out. So now periodically it will come back and run very sluggish and its beginning to really make me mad. Everywhere i take it i cant replicate the problem so that they can understand whats goin on. So now the only thing that i can noticeably see and i dont even know if its not normal is that my oil pressure gauge will peak at around 5000 rpms and will and actually go down in pressure and plateau. This may seem like babling nonsense but any help would save me from loosing it!!!! Any advice?

Re: Sluggish Prelude

leakdown and compression tests are probably not necessary. I'm going more in the direction of ****ty gas treatment product. Probably messed with your injectors, which is why it is misfiring.

Check your fuel line pressure at the rail and get your injectors tested. Sounds like whatever you put in there is gumming up your injectors.

either this ^ or the stuff you put in loosened up enough build up to plug 'em. try a sea foam treatment in your next fill up.

Its a 2000 SH with 100,000 miles. The engine is completely stock h22a4. My car has a few modifications such as full catback, intake, and underdrive pulleyes and thats about it for anything that would even slightly effect engine performance. I just changed my spark plugs but i have not done any compression or leakdown tests. Im a little skeptical about sea foam because i have heard both good and horrible things about it.

I have little experiance with fuel injectors. Would this be something i could possibly do with my edmonds manual or would u suggest finding a mechanic friend to lend a hand?

Re: Sluggish Prelude

Yea so i guess my goal for when i get it out of storage will be to try sea foam. thanks for the help. Hopefully this will be an easy fix. Ha! That was surely a joke. I'm in denial that my car's piston rings are shot. I don't really have the time or money right now to overhaul and rebuild. Plus i'm not going to lie this is the first year i really am getting into cars so i don't have the kind of skill to do it myself. Hopefully in the future though.

Re: Sluggish Prelude

piston rings wont cause a misfire like that.

if theres a mecahnic in your area a company called otc makes injector cleaner napa sells it . stuff works better than sea foam but it wont be cheap.

on the downside you have to have special equipment to use it you cant just pour it in the tank like seafoam.

if you dont wanna deal with +1 for sea foam put 1\3 to 1\2 in the gas tank.

can also use it to clean out the intake

ive done it to my prelude worked like a charm
