I have a 1991 toyota pickup with the 22re and was running fine and all of a sudden it started jerking like it was getting no fuel ive changed mass air sensor ,plugs,wires ,cap,rotor button ,coil,new fuel pump,still does it real bad when it starts to warm up but the last time i drove it it started when it was cold any ideas so i can get fixed?the only thing i havent changed is the fuel filter?any help will be apperciated.also when it starts you can let it idle and it is great on idle when you mash gas down it just bluh!!! this only happens when you mash gas down hard im putting new fuel filter on today to see if that fixes.put new fuel filter no luck it waits till it gets warm before it starts jerking its got me puzzled.

I used to have the same problem; when you give it a lot of gas, the truck sputters and misses. I thought this was a ignition problem, but it turned out to be a head gasket problem. I eventually had to get the head gasket replaced. I even did compression check done on all cylinders, and it came back fine, but the gasket was bad. Have you had any problems with the truck losing coolant, or heating up? Check the coolant levels in the radiator and the overflow tank, and make sure that you're not blowing white smoke. It could be nothing to do with the head gasket, but that sounds similar to my problem, and just wanna make sure you dont ruin the engine.
