Knucklehead97 Posted December 11, 2016 Share Posted December 11, 2016 The injectors plus a new distributor cap, rotor, plugs and wires fixed most of my rough idle. The injectors are great and one of the first things I do to any of my Renix. Link to comment Share on other sites More sharing options...

DirtyComanche Posted December 11, 2016 Share Posted December 11, 2016 You should do the Cruiser tips for the ground cleanups/upgrades/etc and probably even bypass the stupid bulkhead connector too. They cost almost nothing to do and will probably make a difference. Link to comment Share on other sites More sharing options...

Hippie66 Posted December 11, 2016 Share Posted December 11, 2016 I just did the Volvo injectors today. It makes a big difference. I can get you a link to an ebay seller, $69.99 with free shipping. Link to comment Share on other sites More sharing options...

desbennett004 Posted December 11, 2016 Share Posted December 11, 2016 Do you think the coolant temp sensor has much to do with your engine running rich? I noticed my Guage isn't working, ive read from some that it makes a difference while others say it doesn't. Thoughts?

Minuit Posted December 12, 2016 Share Posted December 12, 2016 The ECU doesn't listen to the gauge sensor. The sensor the ECU uses is in the engine block for Renix and thermostat housing for HO. Link to comment Share on other sites More sharing options...
desbennett004 Posted December 12, 2016 Share Posted December 12, 2016 Doesn't the Guage get its signal from the sensor in the block on my renix engine? Sent from my SM-N900W8 using Tapatalk Link to comment Share on other sites More sharing options...
Minuit Posted December 12, 2016 Share Posted December 12, 2016 No. The sensor is in the very back of the cylinder head. Link to comment Share on other sites More sharing options...

ParadiseMJ Posted December 12, 2016 Share Posted December 12, 2016 Renix coolant temperature devices: Sender On the rear driver side of the head, one wire, sends signal to gauge on dash. That's all it does. Sensor On the lower engine block (driver side) sends info to ECU for air/fuel mix. That's all it does. Switch On the stock radiator and most aftermarket rads. Sends power to e-fan relay. That's all it does http://www.lunghd.com/Tech_Articles/Engine/Basic_Sensors_Diagnostics.htm Link to comment Share on other sites More sharing options...
