White_Noise Posted March 29, 2014 Share Posted March 29, 2014 My 1990 is running very rich. I have changed O2,tps,iac,cts,plugs,wires,rotar,cap and cleaned contacts on coil. I looked up the number on injectors 0280 150 217 made for a jag. Are my injectors causing the problem? I'm new to working on fuel injected all I want is a mixture screw.

onlyinajeep726 Posted March 29, 2014 Share Posted March 29, 2014 Are those 19# injectors? If not, I'd recommend Dodge Neon injectors (703's). They're 4-hole and atomize better. A good upgrade over the stock, Siemens injectors that like to leak in the middle. Link to comment Share on other sites More sharing options...
cruiser54 Posted March 30, 2014 Share Posted March 30, 2014 Click on the link in my signature and read post 1. Numerous critical sensors share the same crappy ground circuit. Take care to do all that's recommended there first. I have seen just doing that, an oxygen sensor start working when it didn't before. Link to comment Share on other sites More sharing options...
White_Noise Posted March 30, 2014 Author Share Posted March 30, 2014 The previous owner was like 75 yrs old and did not care how it ran as long as it could pull his bass boat. So going over it changing sensors and over neglected parts. Thanks for the help. Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted March 30, 2014 Share Posted March 30, 2014 I would still advise performing Cruiser's Renix tips because that will likely solve a handful of issues right off the bat. Link to comment Share on other sites More sharing options...
White_Noise Posted April 1, 2014 Author Share Posted April 1, 2014 I found this. So this would mean less fuel than stock correct?
