Having problems with your 2001 Isuzu Rodeo ?

01 Isuzu Rodeo LS loses acceleration after running for a while

\015 This is an ongoing problem..I took to dealer and told service rep what was happening. Left vehicle and he called me to tell me it was powertrain. Luckily I still had warranty on it. Replaced transmission with new one. Car ran ok for one day but next day check engine and check transmission light came on. Called dealer and took it in again. Left vehicle and service rep called and said they had to order a 'powertrain switch.' Again this part was still under warranty. I have 69,500 miles on my vehicle. Picked up vehicle and it ran ok for one day. Took it in to personal mechanic who changes oil, etc. on vehicle. Told him I was having this problem and left vehicle. He called and told me it was the fuel pump and it was only putting out about 10%. So he replaced fuel filter and fuel pump. Before I went to pick up vehicle, he called and said my vehicle needed more work and had to order a 'fuel switch.' Went to pick up vehicle next day. Following day, vehicle had same problem. It appears that once the vehicle has heated up it loses acceleration. I can put it in 2nd gear until acceleration returns and then on to 1st gear. But if I make a stop (light / sign) then I have same problem. Yesterday 7/14 I could barely make it up driveway. Is it time for a new car? I have put in close to $1000 on trying to fix my vehicle. Any suggestions would be most welcome. Mechanic says injectors could be problem now. Thank you!\015 Posted / edited by AnonymousUser on : 15-08-2022

Answers :

This is a complex problem.

Do you have any repair record of the Rodeo LS?

When is the last

ignition module change?

fuel pump change?

fuel filter change?

DO YOU TOP OFF during gas refuel?

Are you able to get the OBD-II codes off the ECU?


I will check fuel rail pressure first to rule out the fuel pump

add Chervon fuel injector clear and fill gas to above 1/2 tank

locate the ignition module and apply GOOD amount of white lithium grease to help it from over heat.

When the truck stall again check the temperature of gauage......Engine should be below 195F

Let the module cool and see does it ran well again.

Good luck
