Last week, my parked car started self ignition "itself". Strange... i thought it is by someone but to my strange, there was no one. When i opened Bonnet, i found Relay installed in ignition(Extra work by Electrician) was culprit.
At the same time, i saw rat coming from under the bonnet. So it might be due to him or another background was that before 5 hours, my car was washed at Service station so may be water or moisture played relay.
Anyways, i took car to mechanic shop and electrician changed relay with Kabli one.
After 1 day, car caused problem in cold start. After starting, rpm stays at 500 and was unstable. After much warming of engine, car was able to move
I took again to mechanic. He told that Low rpm issue at cold start is not related to replaced kable relay & might be due to 2 issues:
1. Weak current
2. Weal fuel pump pressure
After that when he opened bonnet, he saw & told that broken Air filter box(Air filter assembly) might be causing issue as it has repaired 2-3 times before too.
He gave me quotation of 7,500 for Kabli Air filter box(Air filter assembly)in which he told that MAF sensor is costly while additional 1500 will be his Labor charges.
I searched on pakwheels and found that Air filter box(Air filter assembly) Made in Taiwan is available at pakwheels in Rs. 1,800

Now when i told him, he told that it is without maf sensor but new maf sensor is must if u r using new or kabli air filter bx
I am not agree on this and thinking why my old and genuine maf sensor will not work with new Air filter box(Air filter assembly). Is he telling right?
@tintin1
He told me that he has some scanner which will trace whether A/c grip is weak or concerned wiring is short or fusebox has issue. Is such type of scanner available really or he is trying to rip me off
My engine bay is in this condition:
