Ok so I have been following this thread with interest- lots of great information. I haven't had any luck through search for an answer to my question- I have a '97 that has cold start issues. Low idle , stalling, stumbling for the first 1-2 minutes until it warms up- then it's fine. I believe the...
All the sensors that the ECU uses are new- however I think I might have found where my issue lies- I tested the IAC harness for resistance- (3-10 ohms) and it's way out of spec. Looks like I have a short somewhere in the harness between the connector and ecu. ****.
Ok- here’s the deal. When the truck is cold started, it fires right up- idle is around 1000. Within about 45-60 seconds it starts to shudder, idle drops very low, engine surges and stumbles for about 60 seconds or so- sometimes stalls, sometimes comes out of it and suddenly smooths right out. If...
Bump- reviving this thread once more- I have the same stumbling/surging idle with no power- only for the first 1-2 minutes, only when it's full cold start. After inital stumbling/low idle it behaves fine, it won't do it again until it cools down for quite a while. Did you guys ever get it sorted...
OK- I'm getting different answers from different sources, so I figured I'd ask the hive mind here. I have a 1968 FJ45 2 door long bed pickup (square bed with tie down hooks along the sides and tailgate). It has a cab hardtop over the front cab that's open behind the front seats- basically it...
Two things- did you install the Ebay part or the factory Toyota part? If you used the Toyota part you returned the bracket without the internal "key" part that needed replacing?
I have a 2003 with the EXACT same symptoms- when braking from speed to a full stop ( just normal steady pedal pressure to come to a stop, like at a stoplight).
As the speed drops below 10 mph the vehicle begins this strange surging effect, with the surging getting more pronounced as the speed...
