Scotty, after watching your helpful video's I changed the spark plugs and fuel injectors in my 2001 Toyota Rav4 2.0L Gas All wheel drive suv. I took the car out for a test run, after changing the fuel Injectors and spark plugs and noticed very poor acceleration from Idle. (i.e. when I stop in traffic, I really have to push down the accelerator to 3000rpm+ to move a little faster. Once it is running, it there is acceleration.
What could be wrong? can you please recommend what I have to check? Thank You

you could have gotten bad fuel injectors, especially if not factory OEM ones. Also check for any air leaks on the injector seals

Thank You for your response.
