What are the chances that my rough idle and power loss has something to do with dirty injectors on a '90 IROC 350 with 38,000 miles? The resistance on all 8 is 15.9 ohms with little or no variation, but that has nothing to do with whether they are gummed up or not. No codes, entirely new ignition system, erratic rough idle especially when hot, erratic timing with electronic timing enabled, power loss at times, etc. Would it be worth sending them to cruzinperformance or something to get them cleaned, because I can't easily afford new ones right now and the F-rd injectors flow too much? Thanks guys.

 

I did have a problem some time back that sounds similar. My mileage is much higher, but my car acted like it had a fouled plug, but they had just been changed, along with plug wires and it still misses pretty badly. The Chevy dealer told me I would have to replace two bad injectors, but I found out there was a place here in town that could clean them with some kind of sonic cleaner. It worked fine.

 

Thanks for the help, man! Do I need to take them out to get them cleaned, or is there something I can put on that schraeder valve on the fuel rail that will do it without me removing the injectors? Thanks.
