Sounds like like it has jumped time. Probably running retarded (relative point of spark occurrence to piston reaching top of travel).

Have someone check the timing alignment of the crankshaft relative to the camshaft(s).

I'd just about bet it's a going to need a timing belt.

Good luck!

Previa automatic 97 keeps cutting out but not all time


you don't specify petrol or diesel ! If it's petrol (sorry gas ) I would suspect the A.I.C valve requires checking and possibly cleaning, this is the Automatic Idle Control valve, Usaully situated on the inlet manifold close to the throttle body, Cheers

The heater on my Toyota Previa is not working and the temp gauge is not moving even when the car has been running for a while. Please help


the engine cooling system thermostat could be stuck open. This will cause the engine to take forever to warm up, especially in cold weather. The thermostat is inexpensive and easy to change. A new one could fix your problem quickly.

You need to adjust the automatic choke. Your choke may not be opening fully. There is a fast idle cam linked to the choke to keep the throttle open more until the engine is warm. The idle mixture screw is part 37 in the picture, but get the choke adjusted right first, and you may not have to adjust the mixture screw. See adjustment procedures at link beloe.

Hi, I have a 1998 2door accent 130i. Starting fine as usual. as warm up progresses I have what sounds like ignition missfireing until temp meter just starts to show temp increase. Then no more missing and...


yes you hit the nail right on the head there,, its the tem sensor playing you up, its telling the car's computer its warm when its still cold and it cuts back the fule like pushing in the choke,,, this causes the engine to miss fire and lack power till its warm change the sensor

Automatic choke seems to be stuck open When warm car idles at 1500 to 1800 rpm


i dont think it has a choke,it is fuel injected,,change coolant temp sensor it`s not exspensive,,then it could be throttle posision sensor or map /mass air flow sensor ,,,do check air filter before doing any thing and see if it is stopped up or really dirty

No restart when warm audi 100


Do you checked the petrol filter? It can be simple as that.
check the MAF, the spark plugs and cabling, air filter, petrol pump.
I had the same problem with mine (same year, same model), I cleaned all the air intake system, fuel line, and now it's perfect (even needing to change petrol filter, i didn't changed it yet). Careful cleaning the MAF, if you don't know how to do it don't do it, ask an expert near you.
If you can't solve the problem this way, search for air or fuel leaks.

I solved mine cleaning the fuel line and the air intake system.
