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
CutSupreme93 Posted August 23, 2008 Author Report 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. Quote
Doc Posted August 23, 2008 Report Posted August 23, 2008 I would say keep it simple rule. First check plugs and then wires there alot of rub spots. Quote

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? Quote
CutSupreme93 Posted August 23, 2008 Author Report Posted August 23, 2008 ive tried basically everywhere around here they all said its illegal to do and they wont do it. i had it replaced about 5 months ago wit a OEM cat. Quote

Crazy K Posted August 23, 2008 Report Posted August 23, 2008 checked for spark on all 6 plugs??? Quote
CutSupreme93 Posted August 23, 2008 Author Report Posted August 23, 2008 im gonna check everything and anything i can 2mar to try and fix this if not imma take it to a shop and make it their problem Quote
rockfangd Posted August 23, 2008 Report Posted August 23, 2008 sounds like a faulty coil or ICM Quote
Crazy K Posted August 23, 2008 Report Posted August 23, 2008 sounds like a faulty coil or ICM what I am suggesting Quote
CutSupreme93 Posted August 23, 2008 Author Report Posted August 23, 2008 how do i go about checking the coils and ICM? Quote
rockfangd Posted August 24, 2008 Report 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
Doc Posted August 24, 2008 Report 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. Quote
CutSupreme93 Posted August 24, 2008 Author Report Posted August 24, 2008 another dumb questions is 93 octane to high to use in the 3.4? Quote
LuminaPower92 Posted August 24, 2008 Report Posted August 24, 2008 another dumb questions is 93 octane to high to use in the 3.4? Ive used it before, didnt notice much of a difference. Quote
oldscsc Posted August 24, 2008 Report 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
CutSupreme93 Posted August 24, 2008 Author Report Posted August 24, 2008 i asked casue i had filled up with 93 the night before i started having problems. but im gonna take it to autozone 2mar because i didnt have time today and see if there are any codes. thanks for the help Quote
Doc Posted August 24, 2008 Report Posted August 24, 2008 It is possible you might have got some bad gas than. Quote
CutSupreme93 Posted August 30, 2008 Author Report Posted August 30, 2008 took out the coil packs and took them to autozone and they tested fine but i replaced them anyways and all the problems went away running prolly the best it has since ive had it and having 163k miles on it. thanks for all the help Quote
rockfangd Posted August 31, 2008 Report Posted August 31, 2008 very good. It does happen sometimes that they will test good but i always just replace them. Quote
