Dear guys,

When I turn off ignition in my toyota camry 1996, the engine still runs for like 2 secs and the exhausts still bring out gases like twice, shakes a little and turn off. This just started suddenly without anyone working on the car.

Your response will be highly appreciated.
Thanks

2 possible causes.

1. Excessive carbon buildup in a very hot engine

2. Fans wired directly to ignition.

cardoctor:
Your car is suffering from Pre-ignition issues which means the ignition of the fuel/air charge from an extremely heated source prior to the spark plug firing. Pre-ignition may be caused by some other ignition source such as an overheated spark plug tip, carbon deposits in the combustion chamber and, rarely, a burned exhaust valve; all act as a glow plug to ignite the charge.

Your injector nozzles may also be bad and dripping fuel into the combustion chamber after switching off the engine. Have these checked or changed as well.

Thanks will get this checked in 2 days. I actually got a fan fixed and the rewire said he was putting one on relay and the other directly incase d relay fails. However I never thought this could be a reason as he did not touch the engine. Will check this and get back. Thanks for the tips.

Davidlanny:


Thanks guys for your assistance. D rewire removed d cable he connected toward d engine side close to the ignition and connected it to the fuse box and problem solved. Thanks alot.

congrats number 2 worked

you are a demeanour

obekediamondfuto:
oga boss throw more light on the no2 I'd like to know how directly connected fans can cause the dieseling effect

GAZZUZZ:


I explained on another thread previously, but ill explain again.

The fans were wired to (inintion power supply ) directly. To stop an engine from running, you shut down powersupply to engine ecu, coils and any accessories that utilze inition for engine to run.

Fans are usually connected via a series of relays, that way it can be controled (turned off and on) it is also connected to a resistor (not every car), resistor determines speed of fan (slow/fast speeds)

In this particular case, power source to engine ECU and accessories were connected straight to fan (went to jail did not pass go).

With ignition off, fans did not stop spinning, and generated powersupply for a short period of time which kept engine alive.

A fan can actually be reverse engineered to become a small turbine (power generator)

oga gazzuzz,you know any one that want to sell his orobo?I have been searching since two month now with budget of 300k.

you are looking for a problem sir

Boss, you gave me this advice, I have confirmed its the solution but have not been able to carry it out.

The rewires I met says my car system can't be wired such that the fan comes up only when temperature is exceeding 90.

What's the way out Chief! Peugeot D8, XU7 engine

IS IT TRUE DAT CAMRY 01 V6 CAN USE D SAME GEAR SYSTEM LIKE CAMRY 03, 04(BIG DADDY). D GEAR SYSTEM OF MY WIFE'S CAMRY 01 V6 ENGINE JUST PACKED UP N D MECHANIC IS SAYING THAT INSTEAD OF BUY SENNA GEAR SYSTEM, I SHOULD BUY D BIG DADDY'S GEAR SYSTEM. HIS TALKING ABOUT ONE HAVING 10 TEETH N D OTHER HAVING 13 TEETH, EVEN THOUGH I DON'T UNDERSTAND WAT D HELL HIS TALKING ABOUT. I NEED ADVICE.
