question about 9" pro comp lift (new member)
hi guys,
I am 23 and new to this forum, and have always owned muscle cars, never had a truck. I just bought my 98 GMC sierra 2 weeks ago and have a few questions. It has 152,000 km, has a 9 inch pro comp suspesnion lift. The ride is pretty bouncy and the suspension feels pretty soft. Is this normal? I am used to stiff suspension( sorry if its a stupid question) I akso just put some magnaflow mufflers in, and the muffler guy said my truck isnt running right. It seems fine to me, it hesitates very very slightly around 20km/h ( too me it seems like its just the knobby tires) after that its totally normal. The engine light is on so i will have to get that checked. your guys input would be greatly appreciated. sorry im a noob

I am pretty sure its because of having no cats. My mustang had a similar smell and it ran beautifully. I was giving the muffler guy a bit of attitude because I thought I was being over charged. Then he told me it wasn't running right. He also said it smells like diesel, which it does not at all. As soon as I get the CEL code I will post it. I don't really consider a muffler guy as a mechanic either lol. Thanks again for your replies.

Well just to be sure, just take that plug out and then hook it back up to the wire and have it grounded. Then start the motor and see if its misfiring by not sparking. The reason is so you can rule out mechanical. But if your gonna need to change them anyways then go ahead. Let us know how it goes.
