I have Passo 2007. It was in perfect working condition till last weekend. I drove from Isb to Mansehra with no issues at all. Its on Patrol, never installed CNG.
Then on Saturday, my cousin borrowed the car and when he came back in the car was not working properly. It was shaky and it wasn't accelerating at all. when i tried in Neutral gear, it took race after shaky & vibrational start. but i couldn't get it to accelerate.
Next morning, i took it to mechanic. he look at the the engine and then told me one of the cylinders is not working. and i should get it checked from computerized tune up shop. i went to one, he checked and told me one of the injectors (the middle one among three) was clogged. He cleaned it with some carbon removing spray and installed it back.
Now, the car still shaky and no acceleration too, it starts blowing heavy white smoke from the exhaust tip. When i asked "Ustad" why is it blowing smoke now? he replied that because of clogged injector, the cylinder didn't had any fuel. now it got the fuel so now its gonna smoke. To fix it, i should fuel up my car 15liters of patrol and then put engine oil of PKR 50 in the fuel tank and then drive around at high RPMs. it will fix the problem. I didn't do it. I really didn't buy his whole story and the solution. so i came back to the first mechanic. He then changed the coil of second cylinder to the coil of first cylinder and everything settled down. car is accelerating normally, everything back to normal.
But i am worried about the white smoke. Its not there at lower RPMs but when i try the higher RPMs, its blowing white smoke. Mechanic says,its because of the liquid which the guy used to cleanup the injector and the car will go back to normal in few days. It will stop blowing smoke.
Is it right? Should i leave it as it is now? won't that harm engine or anything? or should i replace the injector?
Please help me figure out a solution. or suggest me a good mechanic/workshop/tuneup in Isb who really knows about these cars.
Did any of you ever had this issue with Passo?
P.S: there was no issue at all with car engine before the weekend. No engine oil decrease, no smoke, no pick problem. Infact, it was in water dropping condition.
UPDATE: After initial fix, car was giving me the problem again. At idle, car's RPM was dropping dead low. Engine was shutting off at low speeds. I took it to Toyota Abbottabad Motors. Turns out, one injector was clogged. Only two pistons were working and thats why it was emitting smoke. As they didn't have the new injector, he cleaned up the clogged one. Put it back in, and all was fine. No smoke emissions, and no RPM drops. Back to normal. He asked me to bring the car for a day, its fuel tank is to be cleaned and also the fuel filters. Once done, i should put in Toyota genuine injector cleaner fluid in the full fuel tank and it will be fine.
So, now i am gonna buy injector and replace the one which was cleaned.
Other local mechanic told me that engine is all gone, and i need to change the assembly. Tomorrow i am going to giving him some piece of advice myself.
Any how, thankyou all for the support and your knowledge.
All fine now for the moment
