#105 of 114 94 acura integra ls problem
Feb 19, 2010 (2:51 pm)
i have a 94 integra ls 5 speed an just recently it has started hesitating and jerking and its getting progressively worse. I think it might be an engine problem but im not sure.

Last year I ran the car out of fuel by mistake since my fuel gauge needle was broken and not giving the correct indication to the fuel level.
Since then I've had other issues such as a cracked heat gasket where I had the block swapped out for a 'new' one. I figured the problems with the car would be resolved with this, which it was, until I got the fuel tank to half, at which point the car would nearly die when coming to a stop and idling. Starting is fine, driving is fine, idling itself is somewhat OK (it bounces between 600-750), but the problem comes up with coming to a complete stop. It's almost as if the fuel injection is forced to kick in to get fuel in to the engine.
The other issue since this occurrance is that the engine light would pop up and I'm getting a 43 on the ECU. At first I figured it'd be an issue with the new resonator and extractors I had put on, but then remembered I had this issue last year already before the new resonator and extractors. If I pull over, turn off the engine then back on, the light goes away but comes back on after cruising for a while again.
The engine light will pop up when cruising at a set RPM (3k about, no matter the gear), but driving randomly (city driving) it doesn't come on at all. The idling to near death coming to halt doesn't happen unless the fuel tank is half full.
I have a strong feeling that I have the original O2 sensor (car has less than 100k miles, new engine is 30k), so that'd probably need to be replaced, but I am sure that this is not causing the idling issue.
Any ideas would be most appreciated!

I had the same issue before changing my block since I left the problem for too long.
My issue was I had a crack in the heat gasket between the block and head, which caused coolant to flow in to the engine. The more coolant that got in there, the worse it got.
You can check this by looking at the spark-plugs. If the dirt on them looks like foam/white fluid, this is it.
It can also be the fuel pump on its way out, you'd need to check the fuel pressure and see if what the values are against what you'd expect the values to be.

Sounds like you've got a fuel delivery problem, alright. First, check your fuel lines from tank to underhood to be sure there are no kinks/squashes in it, and consider changing out the fuel filter unless its already been done recently, for all they're worth. If you don't already have a service manual, I strongly suggest you get one - Haynes #12021 for about $25.00 - it'll be a hell of a help, and it'll pay for itself the very first time you use it, by preventing your making silly mistakes by not having the knowledge you need beforehand. After you get the manual for the applicable info, check your fuel pressure, pressure regulator and O2 sensor, all of which you'll be able to do yourself with the proper info.
And it sounds to me like your IAC and FITV need some attention to fix your idling/near-stalling situation; I'd suggest that you do this right after checking your fuel lines and changing the filter, then check out the other stuff, because if the lines are okay, this might be the primary cause of it not running properly thru all rpm ranges; I don't think that getting down to or below a half-tank of fuel has much to do with it. For info on this that you can probably do yourself, go to
Good luck. Give'er a try.

I've owned my 1991 Acura Integra for about a year now. One previous owner, only 132k miles to date.
I'm trying to brainstorm my solution without having to just hand the car over to a mechanic's mercy. Here are two issues. Please reply if you have any suggestions or, more specifically, you know of an experience related to these symptoms. Long read ahead.
I'm having an issue with the idling, almost like it idles too low. Less than 1000rpm. The only time this issue has raised concern is when I occasionally have a backfire from starting the engine and the rpms don't stay high enough and the engine dies and I have to turn the ignition again after about 30-60sec.
Thats my minor issue.
The larger one I'm having is my radiator using up coolant at a much faster rate. I've only had one overheat with this vehicle, and in that case the radiator was almost empty, but not bone dry. I'm not sure when/if the thermostat has been replaced or if the thermostat was compromised in the process. Also, the fans in the front seem to only turn on after the point of exceeded the half mark on the gauge in the dashboard, which it rarely does exceed the half mark. I discovered the reservoir does have a small leak in it.
I wanted to assume either the thermostat needs replacing, as well as the reservoir, at the least. I also considered perhaps the fans aren't working properly as far as when to kick in.
Although the gauge hasn't exceeded the half mark again, I sometimes smell coolant just around the outside of the car after it's been used (30min+ driving). And randomly I see light white smoke/steam, also smelling like coolant, exiting the exhaust. But this happens only on start up after being parked 6-8 hours at work/home.

I am on my 3rd 1990-92 Integra. Mine idles at a consent 750, never any issues with backfire.
As far as the coolant, sounds like a head gasket to me. We did have a GSR that belched alot of white smoke, had a rip off CT Acura dealer take the engine apart, they stated it was the pistons(it was not, they were not fouled or damaged in any way) sealed it back up at a cost of 3000 and then there was head gasket issues, another 1000.
The alternate cooling fan some times turns on my car in the winter, was told there is a sensor for that fan that if it senses a certain temp will run till its cooled past the sensor trip, otherwise unless its really hot rarely get the fan running.
I have found that the computer located under the passengers foot panel, can be the cause of many hit and miss problems. Also check your grounds, which can cause issues if they are no longer attached or corroded over. Can be purchased off ebay, pretty cheap too, just make sure to look at the model number of the one you currently own.
There are CD manuals avail on ebay, cheap too. If you cannot find one send me a email and I will copy mine and send to you.
If you ever get the check engine light turning on and not extinguishing and not allowing you to start the car, that is a definite sign of a bad computer, do not chip it or have some Acura repair shop tell you that they can increase your performance, just get the OEM and you will be good to go.
There are Acura clubs you can contact too that have good info. On my other computer, so contact me back if you need more info.
good luck. I am going to start looking for another, mine has 94k on it, getting harder and harder to find ones in good shape.
#112 of 114 got a question about standard
Aug 31, 2011 (5:18 pm)
i have a 2001 integra standard and when i shift from 2nd to 3rd and in 3rd it starts to shake, but does not happen in otha gears so it cant b the tire alignment. can someone plz help!
#113 of 114 Re: got a question about standard [2001teg]
Aug 31, 2011 (7:25 pm)
Thats a new one. I assume you mean the body of the car vibrates. I have had 3 1990-91 teg's and have never had that issue. Did you get the wheels balanced and have you made sure the balance "leads" have not dropped off?
Is it always at a certain speed? Only when shifting or does it happen when applying brakes? If when hitting brakes make be one of the rods are bent.
good luck. jeffreyc42

Does anyone know what could be causing this?
Any help is appreciated!!!
