Hi

Thanks for using FixYa. Stalling of car uphill suggests that the fuel filter is clogged. You can try to unclog it by removing it. If you found it very hard to clean then i'll suggest you to replace it. Please follow this procedure--

  • Open the hood and look on the driver's side to find the fuel filter. It is a somewhat small canister attached to the fuel line.

  • Disconnect the negative battery cable, and wait 90 seconds or more as a precaution against disturbing the air bags. Remove the protective shield around the fuel filter. If the air cleaner hose and cap and the charcoal canister are in the way, remove them as well.

  • Loosen the lower flare nut slowly to allow all the pressure out. Take off the banjo fitting and the two metal gaskets. Next disconnect the fuel line from the fuel filter. Finally, take the filter out of the mounting bracket.

  • Slide the new fuel filter into the mounting bracket and hold it with the arrow pointing toward the engine. Place a new metal gasket on each end. Attach them with the union bolt.

  • Tighten the flare nut on the lower connection. Put the charcoal canister back, along with the air cleaner hose and air cleaner cap if you removed them. Reattach the protective shield and hook up the negative battery cable. Check for leaks when you start your car.

It is suggested to replace the fuel filter every 30,000 miles, or with every tune up, to keep your Corolla in good running order.




Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

I have a 2001 toyota corolla and I want to know if and how to set the timing on the engine since theres no distributor just ignition coils that sit atop of the spark plugs? Please help! respond quickly!! ...


Well if the timing belt hasent been removed and nobody has played with it then the timing shouldent have moved so,, remove the plug leads all 4 and put a old plug in 1 make sure its got a good earth and turn over engine ,,if sparks the firing order is 1342
from the timing belt end,, other wise check the feed into the coils for power in,if none check with Toyota
Let me know how you get on.........Ron

I have a 2001 toyota corolla and I want to know what causes spark knock in the engine when its under load '' ie '' going up a hill kicking into overdrive etc... I have changed the spark plugs aand used...


The timing of the motor is wrong.ie.the spark timing in relation to the pistons.With the knocking,this usually relates to the timing being to far advanced.As the only real adjustment that can be made is the timing,get it retarded slightly.A very simple job with a timing light.The marks on the crankshaft pulley are easier to see with a bit of white chalk on them.Whilst doing this,check the timing auto advance by bringing the revs up and you should see the marks on the pulley move.If so.All is correct.(when you set the timing,the vacuum advance hose has to be removed so as not to give a false reading)I hope this is of help

If Biggy1 has described it right, I think when you remove the WIRE to the spark plug ( not the plug itself ) and oil jumps out, there is a cylindrical seal that needs replacing and one does not need to even remove the cylinder head.
I have the same problem with my corolla. On the other hand if Biggy meant when removing the SPARK PLUG oil was on the contacts....
