[topher5150]

so I put on a new tps and a new iac to fix the idel problem. it worked for about a day or two, now its doing the same thing again, when I put in park or netural it starts reving up

Did you clean the throttle?

 

[topher5150]

no I didn't. what should I use?

 

[DieselDan]

This happened to me... Unhook the cruise cable from the TB and see how it runs. My cable was adjusted wrong and it was holding the throttle plate cracked open.

 

[BAD97LSC]

vacuum leak?

 

[topher5150]

cruise cable isn't connected can't be that. seems to happen after I've been driving around town for a while. also vac lines seem to be good

Did you reset the computer? Sometimes the learned systems can keep a problem alive even after its been fixed.

vacuum leak?

I bet that might be the problem. I hope to have my intake tube in this week to help my low idle

I had them erase the codes at the parts store

 

[jt351]

you said you had them erase the codes, what were the codes?? also a vacuum leak in a mark 8 will idle very uneasy and slow, not fast. Any ford with a MAF will run slow and lean with a leak, a ford with just a MAP sensor will run fast with no codes. like a 1988 f150.
