dscowell Posted December 22, 2014 Share Posted December 22, 2014 swapped volvo 743 injectors into my truck today along with a throttle body spacer. After installing both items my ideal was ridiculously high. It was around 4500 rpms and after a couple starts it looked like one of my coolant hoses broke a little and was leaking. I have no clue what to do I tried resetting the computer but that didn't do anything. Everything got plugged back in, in the right spot.What are things I could do.I have a renix 4.0L Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted December 22, 2014 Share Posted December 22, 2014 That TB spacer... is it sealed against the intake mani and TB good? Sounds like a huge vacuum leak somewhere within that area. That would be where I'd start. In my personal experience, I try not to change too many things in once instance for reasons like this. When I swapped injectors on my MJ (put Neon 703's on mine), I started and drove the Jeep for a couple days before I did anything else to the air/fuel system. I swapped TB's on mine a few days after that once I determined the injectors weren't causing any negative results. Link to comment Share on other sites More sharing options...
dscowell Posted December 22, 2014 Author Share Posted December 22, 2014 I tightened it down real well and everything should have been plugged back in but checking wouldn't hurt. Link to comment Share on other sites More sharing options...
Dillithium Posted December 23, 2014 Share Posted December 23, 2014 Was the throttlecable installed properly? Not too tight? 4500 is high, almost too high for a vacuum leak. Link to comment Share on other sites More sharing options...
Brickmiata Posted December 23, 2014 Share Posted December 23, 2014 I'm not looking at my truck so I don't know if it's possible but it sounds like the spacer probably extended the accelerator cable. Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted December 23, 2014 Share Posted December 23, 2014 These are both valid points that I didn't think of. I forgot about the strange configuration for the Renix TB. Link to comment Share on other sites More sharing options...
dscowell Posted December 23, 2014 Author Share Posted December 23, 2014 You guys are correct I took the TB spacer out and it fixed the problem. It was pulling the throttle cable causing the high idle. Link to comment Share on other sites More sharing options...

Jeepman Posted December 23, 2014 Share Posted December 23, 2014 There are spacers to lift the Throttle Bracket up the same amount as the TB Spacer so if you did not have them installed then you will need to install them or if you don't have any then you will need to make some make some...

dscowell Posted December 23, 2014 Author Share Posted December 23, 2014 Cool! I'm not going to screw with it for a while but I'll keep it in mind when I install it again. Thanks guys! Link to comment Share on other sites More sharing options...
