cold performance problem
1994 toyota 4runner 4wd, v6, 350k mi., manual trans. new long block w/15k mi. .
1. engine starts fine, idles fine,
2. warm up takes 10 minutes.
3. vehicle does not drive well unless warmed up, actually it is very hard to get out of driveway with small incline.
4. when cold must slip clutch, use hi rpm to get vehicle to move.
4a. it reminds one of driving an old car with a manual choke that is too far out, or one with a stuck choke.
5. gas pedal is very stiff until warmed up. very difficult to depress.
5a. when warm, gas pedal is better but still not the easiest to depress (this has always been the case)
6. when backing off of gas there is gurgling out of tail pipe.
7. when you slightly depress the gas pedal and quickly let off you can hear a slight gurgle pop in the tail pipe.
8. there are no idiot lights on.
9. there seems to be a decided lack of acceleration power when cruising at high speed.
10. when going up hill (I live in the mountains) in 4th the speed is slowly lost with the accelerator pedal to the floor.
have to downshift to 3rd and pick speed back up. which it does fine.
