    EA82 SPFI stumble

    It does sound like it's some kind of electrical thing. I suspect a fuel problem would occur at a wider range of RPM. Weird intermittent things remind me more of a loose connection somewhere. Or as you say, something is beginning to fail. With the "stumble" or "missing" I would also check for loose connections like spark plug wires. Check the distributor and clean the contacts as well. Tracking it down may require waiting until it becomes more consistent.

    Xt6 lost power completely

    Just as a sidebar, so folks can be aware, a vacuum gauge will also indicate if there is a restricted exhaust. A little easier than having to drop the Y-pipe

    Throwing parts at the car is not the right approach. find out what the problem is first. You can clean and sharpen spark plugs. You can clean contacts in the distributor. Cleaning the throttle body and MAF is a good idea, but only if they need it. Inspect first. That could just mean you have an intermittent problem.

    If your engine is not running properly and you want to fix it then you first must get some diagnostic information and make some physical checks. After checking for codes, one of the best things you can do, which is fast and easy, is run a vacuum test on the engine. Here's a couple of links telling what can be learned and how to interpret the gauge. This will help to eliminate whether your engine has any major problems. Likely it does not, but it only takes a few minutes to check. https://dannysengineportal.com/vacuum-gauge-test-tells-you-a-lot-about-the-condition-of-your-engine/ http://www.secondchancegarage.com/public/186.cfm Also, when was the last time it had a tune up ? As already mentioned, check the plugs, check the distributor cap, check the timing, check the air filter and fuel filter. Check the oil and transmission fluid levels. More comprehensive would be to check the engine compression and do a fuel system pressure check.
  5. Replacing all those items means you won't need to do all the physical checks. Focus on getting the diagnostics and repair things that were broken.

    86 BRAT weak/no spark

    Something is clearly wrong there. Perhaps the grounding, the coil or the coil cable. But at least you know where to focus your efforts. You can take the coil in to a shop and have it and the wire tested. If they check out then you have a grounding problem. You can also verify if it is the right coil for the vehicle. Maybe they gave you the wrong one (?)

    I would skip the extra ground wire and simply hold the coil wire (use insulated pliers) next to a ground surface while someone cranks the engine. See procedure from link provided above. If you get a good spark then the coil and coil wire are good. If not then one of the two is bad. That would lead to the next step, the distributor. Are you changing the cap with each new distributor install or are you using the same cap ?

    Seems unlikely that all the distributors would be bad. So I'm going to assume that's not the problem. You have a new coil, plugs and wires.... what about the wire between the coil and the distributor ? A weak spark from the plugs or a weak spark from the coil ? There's some specific tests outlined here chapter 9 troubleshooting for coil/plugs/ distributor. See if there's anything there that you may not yet have tried. http://www.suberdave.com/USMB/HTKYSA.PDF
  10. Some caliper pistons need to be "screwed in". Simply compressing them can cause damage. Check your repair manual to make sure which is yours. If you don't have a manual, check here: http://www.suberdave.com/USMB/HTKYSA.PDF

    EA81 Won't Idle When Warm

    If you don't have a service manual, then to find out how to adjust your carb, look here: http://www.suberdave.com/USMB/HTKYSA.PDF Chapter 7 procedure 12
  12. Step #1 :: Read the codes
  13. So, you can conclude it is not a fuel system supply problem, and it is not a clogged cat. As a sidebar, check the oil to see if there is any coolant mixed in. Maybe a gasket is leaking. It could be an injector problem but I don't know the tests for that. If it is working properly then your back to electrical issues. Are you getting good spark on all 4 cylinders? If so, then you are back to the original issues of the codes and the MAF sensor. Did you resolve if the MAF is working ?
  14. In addition to the fuel pressure test, check the fuel filter. Check to see if it is dirty. Maybe put a new one on if it hasn't been changed in a while. It's possible you got some bad fuel on your trip. Also, try a simple test on the fuel pump, rap the pump with something like a screwdriver handle a few times and see if it makes any difference. Try this a couple of times. If it makes a difference it indicates the pump is starting to fail.
  15. Start here. How did you clean it? If damaged, you will need to replace it. Double/triple check the plugs and wires. Were the plugs new ? gapped correctly ? Are the wires installed in the correct order ? new? Is the cap in good condition-not cracked ? New ? Contacts all clean ? did you check the codes before you did any work ?
