Engine Performance problem
1992 Isuzu Rodeo Question 6 cyl Four Wheel Drive Manual 144, 00 miles
okay, so I have a 1992 isuzu rodeo v-6 4wd with around 144,000 miles on it. When I first crank my car in the morning its goes up to around 1800 rpms. After about 5 minutes it will drop to around 1200 rpms and that is as far down as it will go. I can then drive around and after about 5 minutes rpms will drop to normal.
I can then park car and go shopping and when I crank up. Rpms will go to around 1500, then a couple of seconds later drop back to normal. It has been doing this for around 4 months now. Any help will be greatly appreciated. Thank you
