I had a power problem, when cold idled just fine,when warm it would miss at idle, spudder on acceleration and sound just fine at higher rpm. found number three spark plug wire had burned through lower boot. Spark was firing to head at low idle. same wire burn twice with about 40000 mile between.

    I've had the same problem, take it back to where you had the tune up and tell them to put the right spark plugs in it. Every time i had a tune up they put the wrong plugs in it. It calls for twin ground electrode plugs. check it out, it;ll also get another ten miles to the gallon, if not more

The compression is the same for all cylinders(150), but when I turned motor over, water came out of #1 cylinder only. Any idea?


Sounds like a head gasket leaking water in from the cooling system. Does it run OK? Any water in the oil on the dipstick and a mayonnaise type film on the oil filler cap?

What to do with sputtering and lack of acceleration


Scan for codes stored ion the OBD computer. Many auto parts stores can do this for you at no charge. Based on the results - a complete tune up may be in order.

Good luck!

How can you tell the differences between the cylinder head of a non-super charged and a supercharge Toyota Previa?


Hello. Welcome to FixYa. I am Toyota Ed; I will be assisting you today.

The differences 'side by side' are negligible. The main difference, one that you really cannot determine by the eye, is the size of the combustion chamber. On a supercharged Previa, the compression ratio is markedly lower, because of the supercharged air being sent into the engine. The combustion chamber on a supercharged engine is slightly larger, and the piston domes are shorter.

Note: All turbo and S/C engines have lower compression ratios than a normally asperated engine.

In short, putting a supercharged head on a normally asperated engine will give you very bad acceleration and drivability, due to the increased combustion chamber size. The lower compression of the S/C engine's head on a normal engine will have bad idle, poor acceleration, and bad hesitation.

To tell the difference, you need both variants of cylinder head, and measure the cubic centimeters of the combustion chambers with a liquid. The one that holds more volume is the S/C head.

Thanks for choosing FixYa for assistance today. I hope that my answer helpd you out.

91 Toyota 22re sputters around 2500rpms


your throttle position sensor might me bad or out of adjustment. if it is out of adjustment then it can misfire all the way up to 3500 rpm.
i had a friend that had a miss fire at 2500 rpm. i adjusted the tpss right and the misfire went away. Check for engine codes by jumping TE1 and E1.
Your fuel filter may be dirty and restricting fuel to your injectors.
have your fuel pressure checked.
