sounds like you're having a problem with your valves. they are probably sticking once in a while but under the stress of the load, you're probably experiencing the complete effect of the problem. That is the same problem I encountered with my 98 suburban. I would also here some pinging while pulling a hill. Get a diagnotic check and go from there. I replaced with crate motor and I love it. Hope this helps.
Fuel filter? Air filter? Plugs? Plug wires? Catalytic converter?
The 1998 Chevrolet K2500 Suburban is able to tow up to 6,000 pounds. Standard features include power steering, and tinted glass.
140hp with single exhaust; 150hp with dual exhaust (included with the trailer towing package).
Your trailer tailights are dual-filament, with one being the running lights and the other the brake lights. You need a separate power source from your towing vehicle's brake lights to power them. The easiest way to do this is go to U-Haul and but a set of their trailer towing taillight bulbs for your towing vehicle. The bulbs replace your standard tail/brake light bulbs, and they have two wires coming out of the base of the bulb. One of the wires connects to your trailer's running lights, and the other one connects to your trailer's brake light circuit. I'm trusting that when you re-wired your trailer, you ran two wires from the taillight socket, one for the running lights and one for the brake lights. In some trailers, the brake light circuit also doubles as your turn signals. Good Luck.
When you turn in a tractor trailer (or any vehicle with a trailer), the tyres of that trailer aren't going to take the same course as the tyres on the power unit - they'll go within the turn radius of the power unit. Drivers need to be aware of this, as this can cause the trailer to hit things the power unit would clear, such as curbs, utility poles, etc.
it brings up your shift points(rpm),good for towing a trailer or if you have a lot of weight in the truck.You turn it on with the button near the shifter you have two options normal(uses less gas) and power.
It could be your o2 sensor it reads hot and rich so it cuts the fuel even though you are giving it gas.but does it only when hot /under load. got were they will check for codes for free it should show up
not sure, but most of them have a orange wire and a blue wire run from under the brake booster, to the back. these are perfect for your trailer brake controller and break away power.
Acceleration or towing.
The power button is for towing vehicles.
power loading onto the trailer
check for power at the trailer connector.
