I have an '89 4 runner w/ 22-RE 4cyc, auto, and about 160k miles. The truck has always been very reliable. For some reason as the temperature started dipping (near freezing) last fall, I started having some difficulty starting. First try it just turns over. Second through 4th try it catches just a little bit at the end of about a 3 second try. By the 5th-6th try it tries to start but dies out. Usually by 7th-8th try to starts up. After that it runs great. If I am running errands, it starts fine...until the next morning and the process starts all over again.
I replaced the battery, plugs, wires, cap, rotor about 2 years ago and didn't have any problem last winter. no check engine light or codes. I was thinking there is some sort of extra cold weather fuel injector or some part that is supposed help with cold starts. Any ideas?
