Ok so bout a month or so ago my oil pump went out so I replaced it and now my car is hella surging. So I started checking 4 vac leaks can't find none so I tried re stabbing dist bout a dozen times that didn't help so I changed intakes and gaskets from tb to cover plate still didn't help so I got a new tps and idle air valve still nothing ![[Confused]](confused.gif) it still has same power if not more but if I create a vac leak it idles fine I'm stumpt. Plz help oh ya its a 90 fox for those who dnt know me it has full boltons hci exc

You got a new TPS...but did you set it correctly?
Also, HCI is a pretty generic term. What exactly do you have?

to set your tps correctly, follow this procedure: tps setup
it's not just a plug and play deal. hope this helps.

Coo thanxs guys I'm gonna try the tps thing tom and the map sensor. But I did figure out that it idles fine at first start of the day or after sitting for awhile and while driving stop and go. but say like I stop at the store or sumthing and shut off and then restart after about 5-10min it starts to surge until its driven for a min then surging stops
