1994 Ford F150 Four Wheel Drive Manual 153000 miles
I've got 153,000 miles on my truck, its 4wheel dirve with a manuel tranny. When she starts up she sounds great idle perfect just like she just came off the lot, but when she gets hot she idle very high and doesn't stop until she cools down again. She'll still start up great when she's hot but still idles very high. I took some carb and choke cleaner to the vacume lines to try and find a leak and when I sprayed it over the steel line coming from the exhast to the egr valve the idle got higher. I replaced 3 vacume lines that was so soft they could just colaps, and I replaced the O2 sensor just becuase it had the original factory sensor on it. I was thinking that this might be some sort of temp sensor since it idles high when its hot, but I didn't want to just go around replacing sensors so I thought I'd ask the pros. What do y'all think?
have the same problem?
