It sounds to me like the sensor is bad, check engine light should be on to help diagnoise.

Toyota doesn't publish instructions for that. Its checked and installed for free as a courtesy on an oil and filter replacement, at good repair shops. You took it apart, I'm sure you can figure it out. People that aren't auto mechanics, think everything's so simple.

The poor performance of the car makes these faults to come up and undermine the working of the engine. In this case it seems that the fault seems related with an electric circuit, possible there is no trigger from the ignition unit or there is fauty timing settings.

So to start off we need to check from the fuel tank. Splutering happens even if the fuel contains impurities and specially water. If so this can come up with the pumping when the tank gets empty and produce misfiring, splutter and jerks. So a check on the fuel filter will confirm this as it will be seen, if so remove and clean tank and change the filter. We then come to the fuel pump as the fuel mixing and pressure is determined in this section. You need to have the pump calibrated if the pressure at the injector is low.

Then we must check with the electrics.Since you have changed a whole sett of spares it is important to check the spark intensity .Remove all plugs to check gap and condition of plugs. The black plug indication will confirm that the performance is bad whereas a fully fired plug without deposits must be the ideal view. Check the HT coil and the HT wires, if the intensity is bad this must be swapped and checked to confirm. DO NOT CHANGE any part without a confirmation by trying with a replacement from another vehicle or friend. Finally the LT trigger to the coils must be checked be it from the platinum points or an electronic ignition unit. The voltage of the trigger must be high to give the best HT output.

Now use a strobe to check the Timing on the engine. Adjust if needed to see the TOP DEAD CENTER-TDC- mark. If there is valve noise make sure that the tappets are set properly so that the valves seat firmly for the best compression. Also check compression of engine if there is imbalance on the engine or reduced power.

Thank you for using Fixya

Acts like it isn't getting fuel, chokes out


Hello,

Do you have an engine light? Throwing a code?
Just does this at idle or when driving/acceleration?
Acting strange changing symptoms (E.G.--idle to acceleration to black smoke out exhaust, etc.)? Plenty of Gas in tank?

I am thinking: No engine light
Clog in fuel filter
intermittent fuel pump problem
A vehicle starting sensor (E.G.--Throttle Position Sensor (TPS))
Main computer
Engine Light: Pull Code
Sensor

I hope this helps.

First things first, have someone check the fuel pressure with a gauge.
The EGR valve is not supposed to be open unless the car is moving at more than 20mph.

5 years ago for cap & rotor???? It sounds like it's in dire need of a complete tune up - plugs. wires, cap, rotor, all fluids & filters ESPECIALLY fuel filter. I'd start there and run a good fuel system cleaner through it. Do your tune ups more frequently like every 30K - not wait 5 years!

If You Have A OBD2 Code Reader,It Should Give You A Code And Tell You The Actual Problem,It Almost Sounds Like The Crankshaft Position Sensor Is Not Working Right,That Will Control Your Timing And If It Goes Out,You Will Get The Sputtering And Backfiring.Good Luck....
