Ok. So I jus' bought a 93 SI, it's been sittin' for almost 2 years. It started right up, ran bomb. Then the next day when I went to play with it, it started surging (after it warms up its fine) it blows out white smoke. I cleaned the egr, checked the iat. all seems fine. changed the oil. still need to change the gear oil but that wouldn't have anything to do with the engine, right? well anyway I've never played with a prelude, I've rebuilt HBs but IDK if that's the same. Anyway...What do I do now? It's still surging. Kinda hesitates when u step on the gas while in neutral. How can I get him back in shape? Thx guys!
there's a list a mile long for causes of the surging. start off checking all the vacuum lines, and make sure your coolant is full/fresh. somebody over on honda-tech did a punch list of things to fix. mine was because the idle screw had been tightened down to much and the ECU was arguing with it, loosened down the screw, everyone is happy.
Good lookin out...thx guys! I'll check it out. I think the white smoke is cuz I used disc brake cleaner to clean. It's not smokin anymore. It's still surging but not as much, I'll go do that idle screw thing real quick. The coolant is good. It had 2 year old gas & fluids in it, so I'm jus' redoin everything. Keep givin' me advice cuz I'm new at this & I want my car to be top notch! Thx. Very much appreciated!
get a bottle of the fuel injector cleaner and run a tank of premium through there...that should clean it out good. if the idle is surging, then it probably just needs to be bled. there is a bleeder screw where the radiator hose connects near the rear of the engine
So the surging has stopped. The neighbor guys talked my dude into puttin ATF in my gas tank (totally against me sayin **** no) anyway he did it anyway. I know that thats an old thing they used to do for carbed cars but not needed in today's cars anyway he did it. so im drivin around and it sounds like its backfiring WTF then its jumpin around (no smoke like what others say about crazy amounts of smoke from engine) then it stalls in the middle of the fukin street im tryin to start it but it sounds horrible almost like the engine is seized. how am i supposed to get a 2800 lb car out of the middle of an intersection im a 5'3 chick (imma tough ***** but come on) so these dudes help me to get it to the gas station a few ways down. i play the damsel in distress tell them what happened. they were like oh no ur o2 sensor is destroyed seals r bein eaten cats ****ed. im like seriously!?!? thats scaring the **** outta me (btw he put in a quarter quart or so into a full tank) anyway sorry for the novel but i had to *****! im so heated at him! i ****in hate when he experiments on my cars & not his own. thats why we have our own ****in projects grr anyway...what damage has he really done? do i just run that **** outta the tank? drop the tank? what do i do? pls help i dont want to have to kill my bf
That's seriously messed up. I have no proof, but I'd guess it would cause some major problems. Chances are that it's gonna cost more to get the car running fine than the car is worth.
If you have the tools, I'd drop the tank and get it all out of there, you just might need a hand so that you don't drop the tank and spill gas everywhere.
Alright thx guys! I dropped the tank & drained it las' nite, finished it this morn & filled up with fresh premo. My poor baby, he feels much better now! It's not surging, running good & put some fuel injector cleaner in (all by myself thx very much! ) We are lookin sexy flyin down the hwy now! BF is so never allowed to do anything to my car without my consent from now on! So I have all new fluids cap n rotor spark plugs & wires but still not able to pass DEQ, why? what else do I have to do? It seems like its runnin fine now I mean considering it sat for 2 years. I have 21 days to figure out whats going on. Oh and do preludes always rev high? I mean like at 70 I'm at 3100rpm in 5th, is that normal? Hmm idk. This is my first prelude that ive had so all ur inputs are very much appreciated. thx guys! (I'll get pix up this week so after we get it to pass DEQ u can tell me what else I can do to beat all the Oregon boys lol & make them jealous that my car is better!)
Hey check the aic thats on the manifold thats a honda problem mine does it too but it went away when I replaced it find a used one they are like two hundred brand new
A: ATF can be used sparingly through the PCV valve. sucked up while running it will kill the car and help remove carbon deposits BUT look into a product called seafoam. Used the same way it will clear out carbon deposits and can be used as a fuel injector cleaner through the gas tank. B:Do it like this:
-start the car and get it to Normal Operating Temperature
-leave the car running, pop the hood, pull off the PCV valve from the valve cover
-insert the tube down in the can of Seafoam and let it suck up the amount prescribed in the directions (about 1/3 can if I remember correctly)
-when it gets almost to this point, submerge the tube in the fluid, this will kill the car, and thats OK
-let it sit for about 20mins dead
-start it back up, may take a little longer than normal and may smoke ALOT!!! (may not)
-when it stops smoking, take it on a "spirited" drive (where you wont be embarassed because it will smoke more under load)
some people arent fans and they'll probably speak up, but I've done this on over a half dozen cars, and mileage, idle, and general running have always improved. well, my $.02
Great Thx! Very much appreciated! Im never usin' ATF again I'll check that seafoam stuff out some other time way down the line. My car is runnin like a champ! Except for that ****ty idle. No more surging but it revs high, on the way home I was doin about 100 and it was at 55 6k rpm, that can't be normal right? That's almost redline. And when I am driving regular it revs high, come to a stop sticks at 2k rpm then drops down to about 8 850. It doesn't surge at all anymore now it jus kinda hangs around 2k for about 5-6 secs. Hmm what's that mean? I'll check the AIC like u said. Thx very much for ur help so way appreciated! More advice greatly appreciated ... Thx Guys!
So I went to look at the AIC and um IDK what that is ... I was thinkin u were talking about the ACV but um hmm ... can u tell me what that is & where on the manifold I find it? Thx... Sorry im retarded Im still learnin
on the front of you intake manifold the silver thing that has your injectors and throttle body attached to it there will be like two or three bolts holding it to the manifold with a black part on it and two coolant hoses attached to it every honda guy I have talked to too told me this was the problem it does it on mine so let me know and by the way cleaning it does not help which sucks and by the way be careful with the sea foam I bout did it to mine but after so many miles it can be bad to get rid of all that carbon and create more problems
oh ok yeah i know exactly what u are talking about. that was the very first thing we did was take it off & cleaned all the **** off it. someone else told me that thats probably whats wrong with it. i didnt know what it was called lol. so did i **** it up more by cleaning it? can i get a used one from a junkyard or do i have to get a brand new one? and thx im not gonna use any seafoam anymore i didnt want it done in the first place being that my car has 245 on the engine. but im jus a girl no one listens to me lol. but thx and if u got anymore advice about my car lemme know personal experience or whatever thx!
