Hello All,

Please I need serious help. My Lexus Rx350 2008 model SUV has the check engine flashing. Each time its flashing the power and performance of the engine reduces. I had a scan run on it it complain about the no 3 and 5 coil which i have change with another one,the cylinder misfire. All that can be done has been done even to the extent of changing all the spark and ignition plugs but still the problem persists.

Please what can I do, spending a lot on the car. Could it be electrical problems?and the car is working well before,i just notice the oil is dry and finish quickly,so when it was the time to change the oil for servicing i change both gear and engine oil, at that point the mechanic advice me to ring the engine,so agreed with him,so go-ahead at the same time he condemn the crown-shaft as well, we fix all this,after ringing the given did not bring out the good voice,i was told the timing is not correct they brig the engine down to re-timing it back....at the end of it,the check engine flashing. Each time its flashing the power and performance of the engine reduces and i was told again is wiring problem,some rewire even told me that my brain bus has to replace,please sir/ma someone shuold please assist me ooo......i have spend less that 500K STILL not getting the result ,thank you help your brother,

Let them run a computerized scan on it bro then you google the codes the know exactly what the problems are,if you wait for your mechanic na wahala you go use eyes see..

1. Change your mechanic first.

2. When you get a competent mechanic explain to him the fingering done by the previous mechanic, if he is good, he will know where to start from.

As coil has been changed plus spark plugs, next is to check the cylinders for compression nah him go lead to what is causing your misfire

But the former mechanic miss diagnosed the vehicle reason you are in this quagmire.

Flashing check engine light meant engine was misfiring. Mechanic should have moved plug and coil for cylinder 3 and 5 to another cylinder to see if code moves with it.
If code remains on that cylinder, it would have indicated either an electrical problem (including ecu) or mechanical problem (cracked block, piston, top, etc).

Change your mechanic.
