    A/C & heat cause the engine to surge

    No, all I had was the cheap gauge that comes with the can. I didn't trust it and didn't want to damage anything.

    A/C & heat cause the engine to surge

    That's what I thought. I've learned not to trust the people selling the product to tell the whole truth about the product. "If you want me to take a dump in a box and mark it guaranteed, I will..." Tom Callahan

    A/C & heat cause the engine to surge

    I ddddd.. DON'T need any more chhhhemicals. But I understand completely what you're saying. It really irritates a plumber that chemical drain cleaners (liquid plumber, Draino ... Etc) are allowed to print "will not harm your pipes" on the package when we earn 1/3 of our profit replacing...

    A/C & heat cause the engine to surge

    Somehow just talking to you has helped... Lol. She ran better today than ever during the daily 40 mile commute. Probably unlikely it just took the ECM running time to adjust to the correction made by replacement of the alternator?..... Lol, it's a plumber joke. If it leaks long enough, maybe...

    A/C & heat cause the engine to surge

    Excuse my ignorance (I'm not a mechanic... Plumber by trade), is there a solvent used to clean this? It's a job I've never done, so imagine your speaking to a 6yo..... Lol.

    A/C & heat cause the engine to surge

    Wholly cow! Almost sorry I asked ... Lol. But that's why I've always had my mechanic work on my truck... And trade out his needed plumbing repair. Missing that guy right now.... Lol

    A/C & heat cause the engine to surge

    I meant to ask, is there a scanner you'd suggest over others?

    A/C & heat cause the engine to surge

    I'll try to make a video.... This is slightly beyond normal... Lol. I was told replacing the failing alternator will fix many things. So it would be awesome if all I needed was more refrigerant.

    A/C & heat cause the engine to surge

    When I bought the truck a few weeks ago it had no refrigerant. It had already been converted to 134a so I'm sure it had been charged, just no idea when. I bought a can at Walmart (I know....let the pros do it right) and the compressor started kicking on...."IT'S ALIVE"! But the one large can...

    A/C & heat cause the engine to surge

    The plug wires appear to be new, and since they're just laying however they fell I'd guess they were installed by the car lot "mechanic" (he's not the sharpest knife in the drawer). I meant to change the fuel filter last weekend, but got busy with honey doo's. I hope this truck is worth the...

    A/C & heat cause the engine to surge

    '91 GMC C1500 5.7L (350). I changed my alternator yesterday and my actuators started working. That kind of excited me because they weren't working before. However, now when I turn on the heat or A/C the engine surges up and down a few hundred rpm (estimate because no rpm gauge.... But it's not...

    Alternator amp upgrade

    Hey guys, new member, so I hope I'm in the right forum. My wife and I recently bought our '91 GMC C1500 (5.7 L 350) and I noticed the volt gauge showing low voltage. The truck has had a few small issues that could have been caused by this and I'm wanting to change the alternator asap, but I'd...

    Creating the perfect '91 C1500

    Finally found a group of people with good taste. My wife and I love all the GMT400. After our '89 died we bought our '91 which we plan to build into the perfect cruiser. The 5.7 is strong and with only 139k I'm confident we found a great candidate. The trans has a slight slip between 1st and...
