Have Toyota Questions? Ask a Mechanic for Answers ASAP
hello, thanks for posting
Did this harder starting begin after the parts were replaced? Does it crank as fast as before or slower?
This engine requires iridium spark plugs, platinum should work as well but regular plugs don't work very well.
does the check engine light ever turn on while driving?
Does the check engine light illuminate when the key is turned on?
Ok, what I would suggest then is to have the fuel injectors cleaned or try a can of fuel treatment, when cleaning the fuel system/injectors have the throtle body cleaned, too much carbon building up in the throttle body can cause hesitations and hard starting so I would go there first. Check all hoses from the intake air filter to the throttle body
You're welcome, hope it works out for you. please take a moment to rate positively, thanks.
