So there is a huge story that isn't really relevant to my question here...But the result was that my B18C1 was flooded with gasoline because of a fried ecu. Now all of that is fixed and the engine runs, but there are some issues I am having that I need help with. Basically I would like to know what could be damaged/clogged/dirty/etc because of this. Keep in mind that the gasoline was everywhere (it even spewed out my exhaust the first time starting it). The ecu is now different than it was before...so some of the problems I am having could be due to the basemap in the current ecu (rather than the tuned chip I had in my previous ecu).

But my problems are:
-When I first start it up it will idle really high (about 2k) and then when it starts to warm up it will fluctuate up and down until it finally gets to normal operating temp and it will idle fine.
-It will overheat if I remain idling for a while. I just realized this last night, so I haven't been able to pin point the exact problem yet. But I am pretty sure my fan is still coming on.
-I have a slight whining noise I can hear while idling..This isn't too big of a deal...but if I have my turn signals on, it will whine loud and quiet, loud and quiet (going with the turn signal). Also my headlights will dim and brighten at certain times. I think this is all relative to a bad alternator?
-Just overall, the engine does not run well. It does not run like it did before this mess (gas flooding, new ecu, etc.)
-The exhaust sounds quite different than it did prior to the flooding. Three different people who were around the car often separately told me that it sounded different. It sounds a little louder, but more muffled? It is hard to explain...But I am not sure what could have caused this?
-Also, I have some sort of oil leak close to the vtec solenoid. I will take pictures later.

I am thinking of doing the following:
-new spark plugs and wires
-timing belt and water pump (simply because it is due for a change)

What else do you think I should do to fix the above issues? I want the engine to run healthy again!

 

It really sucks going from a perfectly running engine to this. Please help if you can.

 

if your engine was flooded wit gas and you tried to start it then its most likely f*** up.. your lucky it even starts now.. thats what you call hydro lock

 

I'm pretty sure it is not hydrolocked. But thanks for the input.

Anyone else?

 

up^

 

what ecu did you put in it and is it chipped? the whine sounds like your alt. is taking a crap. You could have washed out the rings.(compression test) Pull your plugs they can tell you alot, like if its runnig on all cylinders, or flooded or if its just one bad cylinder.

 

mine kinda does the same except sometimes it will just die on you. people told me it might be fuel pump. sometimes my car will like sound like its not getting any gas then push the pedal harder and it will kick back in and jerk you is this simliar? and my spark boot keeps popping out

 

Well, I don't think it is anything too serious, because it is still as fast as it used to be. Vtec, Iab's, higher RPMS all seem fine. But I will do a compression test. The fried ecu prior to all of this was a jdm p72 chipped and tuned at church's automotive. After this mess I had to get a new p72 (USDM) and just run a basemap.

 

Is this happening every once in a while during startup? or during normal driving?

 

after starting it like 5 mins later it does it then rpms kinda go up and down then sometimes sink real low bout to die then sputters for a second then goes right back up to 1 then repeats but everyone once in while it will straighten up i got told today that electric fuel pumps will just go out and wont just slowly go out but i not sure on my fuel pump i think its the stock one.

 

Yeah, not sure man. Your issue is a little different from mine. Have you changed the fuel filter? Might not be a bad idea.

 

not yet ill prob go check it now. i just changed the spark plugs and wires. and i gonna get a new cap and button and the guy said if its not that its prob a bad injector do i buy a new injectors or clean them.

 

have you changed the oil?

 

Yeah I have. Does most of that seem like it could be due to the basemap?

 

the funny idle, change in exhaust sound, and weird running; it could very much be the basemap.
the lights and whining sound could be the alternator like stated above
the overheating could be many things. check coolant, coolant flow, thermostat overall cooling system check; if that does not pinpoint the problem move onto checking the headgasket
