Hello. The first thing I would think would be a failed throttle position sensor or a huge vacuum leak or failed mass air flow sensor. Do you have a check engine light on ? How did this start ?

It ran fine then broke down it broke timing belt put new kit on then that's what happened little bit of ruff idle but will idle for hours but soon as give it gas cuts off anytime idle speed change
Toyota Mechanic: Lou P, ASE Certified Technician replied 1 year ago
Oh no, ok so have you done a compression test ? It's possible you bent some valves. That is the first thing I would want to know before we go any further is if compression is good all across the board.

Even though it idled fine a issue can be bent valves , a loose vacuum at the map sensor or a faulty mass air flow or misadjusted tps.

How can I tell if it is a bad sensor I need to have it scanned I guess
Customer reply replied 1 year ago
A non interference can still bend a value
Toyota Mechanic: Lou P, ASE Certified Technician replied 1 year ago
Sometimes the easiest way to tell if you have a bad sensor is to unplug it while engine is running and see if it changes anything better or worse

Is mas sensor on air intake tube
Toyota Mechanic: Lou P, ASE Certified Technician replied 1 year ago
since the only thing that happened was the timing belt broke that tells me that something is loose or disconnected. So we may not even have a bad sensor but we need to try a few things in order for me to understand what may be Happening. What size engine do you have ?
Ask Your Own Toyota Question
Toyota Mechanic: Lou P, ASE Certified Technician replied 1 year ago
What is happening is when you press the gas the computer is not seeing the throttle open or it's not seeing the airflow coming in or it's not seeing the manifold pressure raise in order to add more fuel. Or you simply have a loose ground. We should be able to figure this out. But you may want to run to Autozone and rent a scanner. It's free you just pay a deposit.

3.4 won't stay running at all this morning starts then cuts right back off
Toyota Mechanic: Lou P, ASE Certified Technician replied 1 year ago
ok so maybe temperature is affecting it as well. how long does it run before shutting off? and does giving it gas make it better or worse?

Hello. Different expert here. Please allow me to add input. First, when it does idle, is the check engine light on? I do not see where you said it is on or not. Please advise.
