Engine Performance problem
1999 Toyota Camry 6 cyl Front Wheel Drive Manual 141000 miles
I recently replaced the fuel injectors on my V-6 Solara due to intermittent running/missing problems. The dealer had looked at the car a few times, but finally concluded that injector replacement was the next step, at a cost of $1500. The problem was that the dealer could not guarantee that this repair would solve the intermittent running/miss problem. I was not willing to spend $1500 without some sort of guarantee. I decided to tackle injector replacement myself, and purchased re-manufactured injectors, and the intake gaskets.
I took many reference pictures before beginning to ensure all hoses and connections were reassembled properly. I had to remove the intake air plenum to replace the rear injectors, but this went smoothly.
The biggest problems were trying to remove the filter, and removing the rear plenum support bracket hardware. I now know why the dealer never seemed eager to replace the engine compartment fuel filter, the fuel line fitting was very tight and had rusted in place.
The engine started and seemed to run great. The dealer's diagnosis seems to be correct, the intermittent missing problem has not reoccurred. There has been no further check engine light warnings either. Now, there is only one problem that was not occurring before fuel injector replacement: excessive cranking before the engine starts, hot or cold. I have looked over the engine a few times and compared my pre-repair pictures, I didn't see any obvious mistakes. The check engine light has not come on, so I don't think I left any sensors/actuators unplugged.
My better half wants me to return the car to the dealer, so they can figure out what "I did wrong". I am hesitant only because I feel the dealer probably does not want to get involved with a home mechanic repair. So, please let me know where to begin. Will I need special scanners/testers to check the systems, or are there things I can look at with basic tools.
have the same problem?
