Probably not your problem. When you turn the wheel sitting still the ps has to work to turn the wheels when you're not moving. Since it's an engine accesory it bogs it down a little. With your LQ1 running unsteadily, that bog probably was too much for a sick LQ1 to handle Good luck. Quote Link to comment Share on other sites More sharing options...
CutSupreme93 Posted August 23, 2008 Author Report Share Posted August 23, 2008 i know this sounds like a dumb question but can an accessory belt cause problems like mine? i hope its not the cat again, nobody out here will do a cat delete even though i dont have emissions anymore.

Doc Posted August 23, 2008 Report Share Posted August 23, 2008 I would say keep it simple rule. First check plugs and then wires there alot of rub spots. Quote Link to comment Share on other sites More sharing options...

There are exhaust shops (or speed shops) that will do a cat delete and write it off as "off-road use only". Not the easiest to find though. When was the cat replaced and with what?

CutSupreme93 Posted August 23, 2008 Author Report Share Posted August 23, 2008 how do i go about checking the coils and ICM? Quote Link to comment Share on other sites More sharing options...
rockfangd Posted August 24, 2008 Report Share Posted August 24, 2008 well get a spark plug tester and check each coil pack to see if it is getting strong spark, no spark, or weak spark. Usually a weak spark will be orange and a strong spark will be blue Quote Link to comment Share on other sites More sharing options...
Doc Posted August 24, 2008 Report Share Posted August 24, 2008 I had a int. modual test one time and they said it was good and then I talk to a GM tech and he said that they can can test good but are bad. So I took his advice and changed it and he was right. The point is if your going to take it off to have it tested just save youself alot of trouble and just put on a new one.

oldscsc Posted August 24, 2008 Report Share Posted August 24, 2008 another dumb questions is 93 octane to high to use in the 3.4? Should be fine, a 10:1 CR is high enough to warrant mid-grade or premium but I run 87 octane with no problems. Quote Link to comment Share on other sites More sharing options...
