looking for info on the AFM for my 14 GMC Sierra. SLT i just turned over 100,000. regular oil changes. but. is now throwing code with flashing check engine light. mechanic says it is possibly stuck lifter spring out of # 4 cylinder.....changed ignition coil... nope.....good spark....and now we are at the broken spring scenario. so. after reading I need to have it repaired. and then install the AFM disabler. was going to purchase a Range model. but. when I check to see if it works on my truck it says NO!!! WTH. ok. the Hypertch power stay??
not sure which one to buy
am kind hoping its maybe just a plug. but he hasn't gotten that far yet.
another's out there with this problem. any help would be greatly appreciated
Thanks
Randy
