I Got My 4runner Stuck In A Mud Hole And Flooded The Passenger Side. I've Replaced The Ecu, Starter Relay, And Solenoid Resistor.
Now It Starts But It Only Starts Sometimes. It Has Trouble When It's Cold. When It Starts It Idles Very Rough It Seems Like The Timing Is Off, But If I Rev It Up It Cleans Up And Runs Fine. I've Checked Fuel And Spark And Have Both. I'm Out Of Ideas Some Help Would Appreciated.

Thanks,

22RE or 3.0? EFI or carb?

Rob

 

87 4runner, probably 22RE? ... and you replaced an ECU so its EFI for sure.

=P

 

Did you check all the fuses? Maybe something is shorting out?

 

it's a 22r efi, i checked the cold injector and it sprays so now i'm going to change the throttle position sensor, then after that i'm out of ideas

 

22re efi 5 speed 4x4

 

How far into the engine compartement did the water get?

 

i flooded the half the engine bay on the passenger side

 

Ok... so what does that mean. Did the water cover the relays on that side? I assume no water could have gotten inside the engine, right?

What you've described so far doesn't add up. Missing info.

 

your correct, the air intake was not under water, and i've changed all the relays on the passenger side.
