This days it started behaving funny
Once you crank the engine after a long stall or park. 12hours or more ..it kicks after d 3rd trial .Note it doesn't do like dis b4... Then it kicks and makes some sounds like krak krak krak inside d engine ...dn after 10secs it settles and d sound disappears . It runs roughly like the plugs are bad . after an extra minute everything seems fine like a brand new car... Even when you Rev it sounds cool
2ndly: Once you engage in Drive it jerks you hear A sound like two pots hitting each other from the transmission.Note:the sound only comes once on every cold start...
The car runs fine and moves like a v6 should
Changes from 1-2-3-4 on a smooth role
Now we have two sounds from the Engine and Tranny
I kicked it dis morning and allowed it to get warm
Moved it to drive
And noticed a change in rpm upwards..Dan I released my legs with out even touching the throttle and it was moving on a weird speed even changing gears with out acceleration.
Please your help and advice is welcomed
Tho I will scan it soon

Does your engine turn when you are tryn to start?

He switched on the ignition and cranked it under the hood from the kick starter , the engine was rolling but no sign of it starting
I tried starting it with the key , but it won't even make a sound

The problems with the o2 sensor were the cables
It has been fixed long ago
And the plugs were changed too
It works well , I wiped the codes and for like a month no check engine light

Until October 13 2014 , took the car out , I wanted to climb a bridge , then a sudden loss of power came, I got of the bridge safely without hiting any car, decided to crank her , but no sign of life, I checked the battery it was charged , then rain came , I had to push dt heavy chevrolet in the rain with some road side boys because of my oga Them Road safety and lastma ,I no fit Do explanation for them

She was later towed home
Thank God the next day was saturday
I decided to troubleshoot the vehicle
I swapped the battery with that of my honda pilot
Still no crank
I Scanned it with my tool , no code, I was thinking it was the ecu but since the scanner could communicate I moved my mind away.
Called an electrician
He switched on the ignition and cranked it under the hood from the kick starter , the engine was rolling but no sign of it starting
I tried starting it with the key , but it won't even make a sound
.

lomomike:


@ bolded, ECU = fried. Sorry bro, buy another ecu.

Readonee35L:


Huh okay
But what can cause An ecu to get fried , since there was no wrong connection made or short circuit , or providing wrong amount of voltage to the vehicle
Can it just get fried on its own

lomomike:


Car running without battery can cause an ECU fry, wrong battery connection/disconection procedure also, water breaching any wire terminals can cause short circuit which can kill ECU,

sultaan:
No on that. I will find a video by scannerdanner on YouTube dealt with one of this a bad cop or or ask sensor
