I have a 1990 ford ranger it is hard to start and misses throughout driving speed.

Are you getting a good hot blue snapping spark to the plugs? Also, have you confirmed proper fuel pressure?

Yes I got plenty of fuel pressure. Could any of my problem be in the tps or iac,or e even the injectors are fouled. Im pretty frustrated, k am a mechanic too and not being able to fix this problem is driving me insane.

What are any other possible causes for my problem
