First post, butbeen reading for a wail. My question is. I have a 88 Ranger with a 2.3 EFI.
been haven a problem with a high idel. Changed all kinds of stuff. o2 sensor,TPS, IAM , fuel pressure reg. Well i think I have a handle on it now, but it idels about 1,200 for about 5 mins. then drops to about 750. Is this normal, it's been bad for so long I can't remember what it's suppose to be like.I only set the TPS by ear... Ya know move it, drive it, move it and so on... need help setting it .....
Any suggestions,,, thanks
