speed up problem on start

[Marco1980]

I have 99 Isuzu Rodeo.It takes me too long to speed up .I push the gas harder but it still goes slowly and when it shifts to 2 gear it starts running good with no problems.And when i start going from L and shifting to 2 it runs good.What can be the problem,might be spark plugs???

sounds like something with the tranny. When is the last time you had the tranny flushed? Is it low on fluid? Keep inmind there is no dipstick. The only other thing is the connections on the shift selector contacts get dirty and need to be cleaned and greased.


faulty range sensor?
I've had a problem with hard shifting on-and-off for over a year. It usually happens only in the morning, and is always after the dash light fails to indicate that the truck is in drive. I had the codes read at a dealer last June, and got back a P0705 code. Is this the range sensor malfunction? If so, any recommendations on what needs to be done and where to get it looked at?


I had the same problem with my 99 Passport. I was able to remove my range sensor, take it apart and clean the contacts inside. I remember it was quite dirty and greasy inside. I think they used too much dielectric grease in it, but the contacts were definitely dirty so I cleaned them reassembled it and I have never had the problem come back. The unit is located on the side of the transmission (drivers side) just forward of center. It's been well over a year since I fixed it, but if I remember right to remove it there was a small metal shield that pops off. Then I had to remove 2 bolts and 1 nut that holds the shifter arm and unplug the wire harness (the wire harness was a little difficult to unplug due to the tight space) and the unit will just slide right out. You will need a torx driver to take apart the unit. I wiped most of the grease out of mine; I left some of the grease there so things will slide properly and to keep moisture out. Depending on how dirty the contacts are you can clean them with a pencil eraser or a very, very fine sand paper. Don't spend the 90+ dollars for a new one this is a fairly easy fix, once you see the inside you won't think it's worth the price tag! It should take you about 45-60 min to repair.
