SOURCE: dies while idling and gas surges going slow

I don't know about the smell of gas, but we had the same problem. the first time it happened, (I don't mean it happened once - it happened repeatedly) a bottle of fuel injector cleaner solved it,

The next time it happened ( a couple years later) I was stranded at the first red light when I got into the city. The car would stall each time i put it in drive. It would idle fine i neutral & park, but stall in and other gear. A guy stopped to help me - he was from a reputable transmission chain. he said the problem was with ? ?? in the transmission ( I can't remember exactly 0 it was about years ago) he fiddled with a switch that locked up in behind the drivers side front tire. he couldn't get it unlocked, so the car was towed to his transmission shop. They repaired the problem and I have not had this issue since!

SOURCE: 99 hyundai accent engine surges and dies at start when cold

There a lot of cuses for this but you need to scan the vehicule before to know what sensor is having troubles, if is too much expensive the scan in your city consider to buy one. I see in ebay a lot of types of OBD2 scanners for $25-30!

SOURCE: why does my 1989 chevrolet s10 surge and idle up

You may have a bad idle air control valve, I would also check for a vacuum leak, from a vacuum hose or a broken vacuum tee.

When I start my odyssey it starts surging. I found a small rubber hose on the right side of the engine, but don't know where the other end of the hose goes....Help


WHAT COUNTY???????????????????????????????????
hot engine, cold or both?/// a key question
WHAT ENGINE: ( usa list , ONLY)
2.2 L F22B I4
2.2 L F22B6 I4
2.3 L F23A I4 2.3 L F23A7 I4
the fsm covers this. hose thing.... all hose can be followed,
unless its axle vents on 4wd cars. (they go no where, special)
is surging the only symtom.?
no engine stalls.?
lack of power in any gear or hills.
no misfiring?
no flooding.?
starts easy/?

ok what is surge, that it really is idle controls bad or out of comtrol
1: idle controls bad. (isc dead?)
2: or engine is running way too lean, and ISC cant keep a grip on idle.

easy huh?
and #3 misfiring so bad the idle controls fail.
are all fuses good?
is the CEL lamp glowing , then goes out running engine.
no , the scan it. or do the flash DTC codes trick.

a good tech ,first finds out if the engine holds closed loop status
hot. at idle, if not, he fixes that first.
as he/she knows that idle is the last thing to work right, in EFI.

one other way to get surge is air leaks (aka. vacuum leaks)
if the engine (unsaid option) is MAP based, it will race fast
with any vacuum leak, and it dont take much of a leak
to make the ISC idle controller go nuts.

so repost , hot/cold both questions
and actual RPM numbers. we need numbers
is the dash Tachometer missing. ????
and what engines in car.

all lean engines surge.
all ISC systems can surge if out of control , not all do this. just 1/2
if the ISC surges, it means its trying hard to gain back control.
this is called a software servo loop.
The ECU is programmed to hold rpm near say 800 RPM hot.
and is very digressive in that role.
I have a 91 car that will surge, with any vacuum leaks.
(by design) depends on which engine.

What can make the car surge for over 2 years and the OBD2 machine does not pick it up?


It is not always a case of plugging in the code reader and the codes come up. There are different cables to use for different data plugs and certain procedures to get the codes to read . There will be a fault code recorded and you may have to take it to a dealer service centre to have their machine read the code.

Idle fluctuates


Its could be a few things. Most likely cause is you IAC (Idle air control valve) If this valve gets clogged up with carbon it will cause a idle surge on cold starts like you are describing.

Next your FITV (fast idle thermal valve). When the hot wax inside of this valve starts to wear it will cause a idle surge on cold starts.

Power surging


Try cleaning the idle speed control airbypass valve, they get sludged up and cause this kind of idle problem.
