vacuum

Thanks to anyone who can help me figure this one out. I have a 2008 Dodge RAM 1500 with a 3.7L V6 and 145,000 miles on it. I run the truck 50 miles every day. Sometimes, about twice a week the engine will stall at a stop light or stop sign. The truck will start right back up and runs rough for...

Hey guys -- I really need help on this -- there is a small tube (made of hardish plastic), that comes out of the firewall on the starboard (that's right-side when facing forward), side of the engine compartment -- the small tube attaches to another tube that looks like a vacuum hose. However...

Air mixer works. Blower works on all settings but when I switch to defrost it keeps blowing out the dash and won't go up to the windshield. I think it's a vacuum problem. There are 2 vacuum lines hat go through firewall that are heater related. One is grey and connects to my coolan lines and the...

So, my '85 D150, with the 318 5.2L motor dies once it has warmed up. I assumed it was the O2 sensor, so I went looking in the exhaust manifold. No O2 sensor?? There are only three intrusions into the manifold or pipes. The first two are ports for the Air Injection System. The third is on the...

Hi, I recently bought a 2001 Ram 1500 with the 5spd manual and 4x4. The day after I got it home I changed all the oil :engine(5.2),transmission(NV3500),transfer case(np231d), and both front and rear diffs. Everything runs perfect on the truck except the 4 wheel drive. The front driveshaft...

I am in need of some advice. My truck runs rough and is sucking massive amount of air through the IAC. It always starts and idles fine but after a few minutes it starts to run rough and sounds like there is a major vacuum leak, which goes away after another minute or two. I have changed the IAC...

I want to make the air conditioner in my 2011 ram colder. Living in an area with heat indexes at 100+ degrees in the summer months, the typical car or truck A/C just can't keep up. In a previous truck I had I by-passed the heater core with a vacuum actuated valve. The valve would open &...

Hi all, My 2500 has developed problems on the first start of the day and has been spending more time at the mechanic than at home. What would cause engine low vacuum ( a steady 15 on the gauge ) ? No fault codes come up even when the engine floods and surges on the initial start-up. I have...

I have a '98 Dodge Ram SLT, and the air only blows through the dashboard vents. From what I have read, this likely means there is a leak in the vacuum hoses somewhere (and the default vent is on the dashboard). Is this true? If so, what is the easiest way to find the leak? Thanks!

I am having trouble with my engine. It starts but won't stay on unless I hold the pedal down. I have researched this issue and keep hearing about "vacuum leaks" but I must confess, I am NOT a mechanic and don't know where to start looking for this issue. Can anyone help with this...preferably...

I just purchased this truck yesterday and coincidentally we received 7 inches of snow as soon as I pulled it off the lot. It's a 1998 Dodge Ram Sport 4x4 with the 5.2L V8. I got the truck home and then when trying to pull back out of the driveway the rear wheels started spinning. I shifted into...

Hello Everyone, I recently installed an aftermarket radio in my 88 Dodge D100. Afterwards the vent control no longer worked. Everything comes out of the center vents. It does not matter if I select defrost, vent, heat (floor), etc, everything comes out of the center vents. After doing a bit...
