SOURCE: chevy s10 broken vacuum line

The plastic line in the wiring harness goes to the heater controls; and believe it or not , the other end goes to the vacuum tank - but its in the FENDER !!!!! behind the ABS, kinda under the drivers side hood hinge - great place to put one ain't it ? No wonder GM is going broke !! Good Luck

2001 Chevy Silverado 1500 4.3L V6 was running fine and then the O2 Sensors went out. I have since replaced them but it with start then idle really rough then die if you let off the gas


Robert, have vehicle scanned for diagnostic codes. Check for vacuum leaks and if you have not done recently give vehicle a complete tune up cap,rottor,wires,plugs,filter's,etc, including injector/throttle body cleaning. Check the attached links,instruction and guides, Good luck

My 1995 chevy s10 idols fine until engine warms up. Given gas it lugs down and dies. Changed fuel pump&filter,tps,cps,oil pressure switch,Vaccumm lines. Had it scanned. All that showed was bad relay.


You will need to have the computer scanned and monitor the data stream to see what is happening. The 02 sensor info will let you know if the engine is over/under fueled and what may be causing it. Throwing parts at it by just guessing gets expensive. The data stream, if viewed by a trained technician, will reveal any problems that may be causing your problem

1999 chevy lumina rough idea after warm up


It could be several different things causing this, my first guess would be to look at the EGR port going into the intake. Most times it will clog up and can cause rough idling. You must know how to clean it properly, the EGR valve will have to be pulled as well as the throttle body in order to clean it properly. Also, check for vacuum leaks. It could be other things as well but this is where I would start. Hope this helps. Thanks, Allen with Morgan's Auto Repair 912-282-1602 Waycross, Ga.

I have a 1993 Blazer S10 4.3 vortex. runs pretty rough once warm and also the brakes will get exstreamly hard to push at times.


check for vavume leaks or cracked vacuumed line or fitting
power booster may also be bad not holding vacumed
for power breaks
best way to check with oxygen bottle very little pressure and
folow suspected area rpm will incress when leak is found
also propane torvh will work but be carfull both are flamable
once located repair area

2002 s10 zr2 runs rough bogs down when you


First check for any cracked pipes leading into the intake manifold If all OK (with no codes showing it probably is OK) try checking the fuel pressure regulator. If you smell fuel from the pressure regulator vacuum side arm (when the vacuum line has been disconnected) it needs to be replaced.

Rough idle on 1999 chevy cavalier z24


Check for vacuum leaks. Spray some carb cleaner or WD40 around the intake manifold, trottle body and any vacuum lines. Check for loose connections on engine wiring harness (Maybe you disconnected a sensor, and forgot to re-attach it?).
