Not to be to cliche...but Help please. So here is the full run down. About a year ago my Yukon started what i can only call a severe hesitation, it got so bad that i took it to the dealership. They had it for a month and a half and claimed to have replaced everything but the computer with "known good" parts. I was unwilling to spend 2000 on a computer and reprogram that may not be the problem. This year it got so bad i bought a computer from LKQ and had it programmed by the dealer. It seemed better but never went completely away. I have since replaced the throttle position sensor, Maf Sensor, Cleaned the K&N filter and completely cleaned the throttle body, all of which the dealership claimed to have already swapped, but I just couldnt believe that once all that was done it didnt fix it. I considered trading her in, but just cant part with her. She has no codes and idles fine, its just when I press the pedal it feels like its just bogging down. It is odd to me that when I replaced the computer, and cleaned the maf it got so much better. I am desperate. My hope is one of you is that guy who knows everything and know exactly what it is. I have read every forum i could find and just cant find anything that matches my symptoms exactly. Please Help, Thank you in advance -
I've carried my 2006 Suburban (123,000 miles) to three shops and one dealer now to avail. The engine stumbles when accelerating and struggles going up even small hills or bridges and struggles to accelerate. I'm $1600 into this and still have the same problem. I have replaced all 8 coil packs, plugs, wires, upstream and downstream O2 sensors, catalytic converters, Throttle Position Sensor, accomplished compression test (approx 190 lbs on all cylinders), fuel pressure test, dealer cleaned intake, dealer cleaned fuel injection and rails. The private shops kept the truck for three weeks and after not pinpointing the problem advised me to carry it to a dealer. They charged me nothing for labor and discounted the price of the parts. The dealer kept the truck for four days and came up with something different each day. Wanted to charge me nearly six hundred dollars but settled for $260. Dealer advised tearing down the top end (makes no sense as compression is good and holds for over five minutes) for $800 and then another $2000 to reassemble if no problem found. Is this something anyone else has gone through? I use the Suburban to tow a camper but there is no way it has the power to pull itself much less a trailer. I hate to say it but I beginning to lean towards buying a Toyota Tundra if I don't find a solution to this problem soon. I really like my Suburban but I can't afford to throw more money at guessing what the problem is.
