My Toyota Camry 07 gives me a slow start in the morning and jerks. When I get on the road and drive for about 10 mins it gets good. If left for about 4 hours again it gives me the jerk and slow start.

My mechanic has changed the fuel pump and filter and serviced the nozzle. He also checked the plugs still same. Yesterday the check engine light came on and I think at this point it is necessary that I seek help and get the car scanned. I will appreciate if anybody can recommend a good mechanic at the iyana oworo axis who can scan the car to detect why the check engine sign is on. A cost effective mechanic too because the situation is getting really tiring.

I have also expended much in the issue already. How much should I be looking at to scan the car?
