ANDY Posted July 22, 2010 Share Posted July 22, 2010 hey guys i have a problem i just washed and detailed my 87 pathy yesterday and i drove it about 45 miles and on my way back home my pathy started to misfire and run really rough it stalled on me at a green light then i pulled over and it didnt start back up for a bout 5 minutes and when it did it idled perfect then i started to drive it and it started to bog out and misfire really bad and it started to blow out black smoke. my spark plugs all look ashey i have no clue whats going on and i was wondering if anyone on here has had the same problem or could help me figure this out. any help would be appreciated andy Link to comment Share on other sites More sharing options...
MY1PATH Posted July 22, 2010 Share Posted July 22, 2010 (edited) Based on your wasing and haing trouble right after I'm a start with; get any water under the hood?(wash the engine bay?) the Pre-90 were more prone to misfires if too much water or even vapors got under the dizy cap(points are too close together) Check all your connectors are dry aswell... The initial misfires may have lead to the ash deposits (fireing way too early with incomplete mixture) which of course cause fouling....

nunya Posted July 22, 2010 Share Posted July 22, 2010 gotta agree, you got water somewhere you shouldn't have and it's having issues goeing away. I silicone my cap every time I pull it to help seal it and keep the old h2o outta there. Link to comment Share on other sites More sharing options...
ANDY Posted July 23, 2010 Author Share Posted July 23, 2010 i took my cap off looked dry but then again the points were kinda rusted but i have a feeling its something else but im going to try to work on it tomorrow after work Link to comment Share on other sites More sharing options...
GrimGreg Posted July 23, 2010 Share Posted July 23, 2010 Check for nicks in the plug and coil wire insulation, and make sure the connections are good. Check that the plastic casing on the coil isn't cracked (what was wrong with mine when it acted like your's is). Link to comment Share on other sites More sharing options...

Kingman Posted July 24, 2010 Share Posted July 24, 2010 Did you check your MAF sensor and the connections? Being you pressure washed the engine, there's probably corrosion starting in some places. Link to comment Share on other sites More sharing options...
ANDY Posted July 26, 2010 Author Share Posted July 26, 2010 (edited) hey well i checked my codes and its a 44 and i believe that means no codes but when i start my pathy it fluctuates 3 times and then it dies, has anyone had the same thing happen to there car? if it was my MAF wouldnt a code be showing? i just read another topic and i think my truck is in safe mode , and do i have to put it in mode 5 to check and see if my MAF is wrong?

ANDY Posted August 5, 2010 Author Share Posted August 5, 2010 anybody have any ideas why my pathy will start then die immediately? and Do the tps go out on the TBIs a lot? this thing is kicking my butt right now and cant think of anything that would make it go out like that Link to comment Share on other sites More sharing options...
jprater88 Posted August 6, 2010 Share Posted August 6, 2010 (edited) change the distributor cap and the rotor you more then likely have corrosion on the contacts in the cap its the same symptoms mine had trust me... It seems weird but if you can take some sand paper to the contacts and clean them off and to the rotor also i bet you see an improvement... if so then there you go... EDIT... Mine was "auto reving" also thats why i thought that it was something else too... I would bet 100 bucks that if you do like i said you will have your answer...

ANDY Posted August 6, 2010 Author Share Posted August 6, 2010 yeah dude im probably going to try that tommorow after work and also clean my MAF sensor and if that fails might try to change my TPS , but so yours is working better now? Link to comment Share on other sites More sharing options...
jprater88 Posted August 6, 2010 Share Posted August 6, 2010 yeah it runs perfectly fine just like the day that i bought it which was only about a month ago but no issues now.... If anything she runs better Link to comment Share on other sites More sharing options...
ANDY Posted August 9, 2010 Author Share Posted August 9, 2010 i think i fixed my pathy my MAF sensor was dirty so i cleaned it with carb cleaner and that thing fired up perfect didnt stall and let me rev past 3k but i still need to test drive it, but anyways im happy now time to go camping Link to comment Share on other sites More sharing options...
