Need help with code 25
hope some of you can help me out. I have a 88 s10 with 4 cyl. starts fine and runs good cold but when it warms up it starts stumbling and cutting out, its hard to keep it running. I changed spark plugs, cap, rotor, plug wires. It still throws code 25. Any Ideas ?

Re: Need help with code 25
I did a bit of searching and I found a code 25 is a Intake air temp sensor error. Is that what you have a code 25 as?

Re: Need help with code 25
Check for a broken or dis connected wire. I believe on those its in the air cleaner housing. If that all looks good replace it and clear the codes. It should be fine after that. I had the same problem with my astro van when i put the small block in.

Re: Need help with code 25

Re: Need help with code 25
Thanks guys, yes it is a 2.5 and my plan is to replace the intake manifold air temp sensor and go from there.
