    89 2500 - Severe Cutting Out - MAP Sensor Issues

    I doubt this is related, because it is running incredibly strong while cold (tons of torque, and proving it can run smoothly through the rpm range), but this motor has a ton of blow-by). The PCV lines smoke like a chimney when disconnected, so the oil rings are shot. I thought maybe all the...

    89 2500 - Severe Cutting Out - MAP Sensor Issues

    I just bought an '89 C2500HD with the 350 motor (276K miles). It was running fine during the test drive. After taking it for the first drive after getting it home, it started cutting our hard...could barely get it home. At first, I was convinced it was fuel related. I thought maybe fuel...

    Newbie - Can I Tow 4,500 lbs with my Cheyenne K1500 5.0 Litre 5-Speed Manual?

    Interesting. I wonder why it drops so much with the manual tranny. It's 5K with the 5.7L motor with the same manual trans. And it's 5K with (assuming the) same auto trans with both the 5.0 and 5.7 L engines. So where's the weak point? Simple deductive reasoning leaves me nowhere...telling...

    Same 5-Speed Manual Tranmission with 5.0 and 5.7 Liter Engines in the '97 K1500's?

    The sticky doesn't say. I just bought a '97 Cheyenne K1500 with the 5.0 liter motor and 5-speed manual trans. Does anyone know if they used the same *manual* trans with both the 5.0 and 5.7 liter motors? And either way, what is it? I thought I read that someone thought it might be a Tremec?

    Newbie - Can I Tow 4,500 lbs with my Cheyenne K1500 5.0 Litre 5-Speed Manual?

    Okay. I'm just curious to know if I'll be able to drive at freeway speed w/o keeping the pedal buried. I guess I'll find out. To reduce the tongue weight, is it better to have the car facing backward or is that dangerous to have more weight at the rear of the trailer? I have to find out if...

    Newbie - Can I Tow 4,500 lbs with my Cheyenne K1500 5.0 Litre 5-Speed Manual?

    Looks like I can do it, according to this forum thread: http://www.gm-trucks.com/forums/topic/115662-how-much-can-i-tow-with-my-1997-gmc-1500/ He doesn't specify which transmission he has, but I'm assuming it won't make that big of a diff.

    Newbie - Can I Tow 4,500 lbs with my Cheyenne K1500 5.0 Litre 5-Speed Manual?

    I just today bought a 1997 Cheyenne K1500 4x4 with the 5.0 liter with the 5-speed trans with 138K miles. I’m curious to know if I can realistically tow my car (1987 Buick T Type) on a trailer long distance…1,800 miles with it. I see that the GVWR on the door is 6100 lbs. My Buick weighs about...
