Car acceleration and misfiring when wet problems!?!?!??!?!?

Your wetness problem could be related to moisture getting into the distributor. I had issues with that until I sealed the distributor cap with RTV silicone. You might check all of the new wires to see if any are not seated well, allowing moisture to get under the boots.

2d attempt... ok, that's a annoying one, yet could prefer to make a pair techniques. a million:It "could desire to" be attainable that decrease than load that leaking AIR plug could desire to be certainly performing as a venturie and sucking exterior air into the exhaust pass. this could be inflicting the O2 sensor to be examining a lean burn concern, whch could reason the ECM to offload greater gasoline into one cyl intermittantly. as quickly as you enable off it, popular firing could sparkling the plug, so all the plugs could seem popular. 2: yet another possibility could desire to be an injector coil. If a form of starts to fail, it may desire to reason an intermittant missfire decrease than load at bigger RPM. you are able to meter them and see if one has a various resistance then the others. 3: it is likewise attainable which you've got reached the modification element on the engine that the inventory ECM can no longer handle the needs of the engine with no better overall performance chip blow. i do no longer "think of" you have an electric powered difficulty as you're no longer storing any codes. Did you save one whenyou unplugged the MAF? gasoline issues normally only do flying codes if any. consequently, i could propose you detect a dyno save that still has OBD1 purposes, strap it on the dyno and reproduction the project there. in case you are able to no longer detect a save with that, you will purchase a tuner set up that works only besides (i exploit Moates). I had to purchase dyno time placing my '87 up, yet had to grant my very own tuner software for it. i be attentive to this sounds costly, however the tuner software/hardware is approximately $3 hundred and dyno's in my section run approximately $350 an hour. With the dyno's extensive band O2 set up, it may probable take not greater then an hour to good diagnose the project AND tweek your ECM for optimum overall performance. that's $650 for a restoration. you have spent greater then that already, and you're able to have the tuner for destiny use as you construct the engine. playstation : in spite of the undeniable fact that that's a soreness interior the patute, I switched from a MAF to a MAP. It consists of a rather substantial twine replace and reprogram to the ECM. I did it, yet i replaced into the knowledgeable monkey. A overall performance ECM builder gave (bought) me the technique and mandatory hardware.
