Esteem Hard Starting & Stalling

[Fab]

1999 Esteem Wagon GL, 1.6l, 5spd manual

Hard to start.... takes several attempts to start (worse when hot). Then runs well while driven, but when idling it will stall. Have kept the A/C on (slightly increases idle rpm) and has helped a bit. Any ideas/thought? Air filter has been cleaned, plugs replaced, oil changes as required.... Maybe fuel filter???

A while back, the check engine light was always on. ODB reader pointed to O2 sensor.... I replaced the sensor and reset the light. Now the check engine light is gone but still have starting/stalling problems.


Anyone have/had these problems? Appreciate your feedback.

Thanks.

Replace the fuel filter, and then maybe look into getting the injectors cleaned.
Edit; if it has a replaceable FF, mine does not.

Had some problems like that on my 1998 Esteem 1.6 The IAC(Idle Air Control) motor gets all gunked up with exuast carbon and needs to be cleaned. It will get stuck from time to time causing symptoms like you speak of. This is generally done by removing the Throttle Body. DO NOT REMOVE THE IAC SPECIAL SCREWS!! OR YOU CAN DAMAGE THE IAC!! Youll know them when you see them they resemble Torx........Use the other ones. Spray some good carb cleaner and use a q-tip and clean the carbon out of the passages. Reassemble and this should take care of your dying problem.

Had the same problem with my esteem 2000, 1.6. It was a clogged EGR Valve.

you may have a fuel pump strainer problem or the fuel pump itself, when your car stall again check if fuel pressure is present in the fuel line or open the fuel filler cap and check if you can hear a hizzing sound when you switch your key to ON..

i have an esteem 97 wagon 1.6 auto, and having the same problems, i went to a chop shop and had the IAC changed about 6 times (they have a lot in stock) but problem was still there(dunno if all the 6 IAC are broken), finally we tried to replace the full throttle body complete with IAC and TPS they had 3 in stock and all did not work problem still there. the chop shop imports half cut cars fron Japan.

Some of these fuel pumps are known to act up after 8 to 10 yrs, try replacing yours!!
