I bought a 1992 toyota pickup with a blown headgasket thinking I would just replace the head but I found a 22re for 300. I swapped the motor but a few clips were different so I swap the cold start injector from the old motor to the new one and throttle position sensor it also didn't have the air box with the air volume sensor so I got one used and the guy said he adjusted it a bit to run a touch richer. I got it all together and it ran great for about 150 miles then I started having power loss at high rpm. Then I got it home and now it starts fine usually sometimes it just fire once and won't start. It gets up to temperature just fine but when I turn it off it won't start until it cools back down. Can anybody help if so I would be very grateful thanks!
