Help!!
I know it isn't a truck but maybe...
I need help.
88 sefi and computer off an 88 tbird.
I have replaced the Map sensor , EGR valave , EGR sensor , TPS sensor , PVC valve , ICS , and the TAB.
The car idles fine when cold but as soon as it warms up it starts to surge from 950-1200 . If I bring the rpms up to about 1500 it smooths out fine.
What could possible be the problem?
I am at my wits end. I am really considering just driving it off a cliff .
Someone please please help!
Email me or instant message me (preferably cause we can discuss it in real time)

Help!!
Replacing parts without having the codes, is like, well, looking for a needle in a haystack when it is pitch black outside.
But, from what you have said, I would tend to think that it might be an O2 sensor.
You can look HERE and it might have the directions to pull the codes yourself. But as the previous post said, you can get most local car parts stores to pull them for you for free.

replace your coolant temp sensor the two wire one (for ecm). other one is a single wire one its for your temp gauge/idot light.
If the ecm thinks your engine is either colder/hotter than it realy is (coolant temp sensor out of range) then it gives you the amount of fuel for the incorrect temp and thus engine runs better at some temps and not others.. Ohh ya you said it runs better cold so your O2 probably even being used, it only comes into play once your engine is up to a certain temp...
