Hey all, recently when trying to start the ls not matter if it the engine is hot or cold it fires up and drops down to 200rpm and barely wants to run. If I hit the throttle and take it to about 2000rpm then let off it goes to 850 rpm idle. There are no trouble codes in the computer. I have tried another ECT and there is no change. I have also cleaned the FITV and the IACV. Any tips greatly appreciated.
service the TB? just throwin that out there
I guess I’ll just go after it with some fuel injector\TB cleaner. Thanks.
You have properly adjusted the idle with the “idel adjusting screw” right? Lol! Helms manual apparently needs a spell check.
No I used the Idol adjusting screw.
Check the exhaust system it sounds like its getting clogged…try disconnecting your down pipe and start your engine see if it idles up. if it does replace your cat and remove your resonator…
I had this problem before…let me know how it works out for you.
I’ll give it a try. Thanks.
