Weird missing problem!!
alright i have a weird problem! I had a ---- load of problems with my car... problem after problem... I had a weird cutting out problem u guys might of remembered. blah blah found out i think it was the head gasket. Changed head gasket etc ran ok for about a hour....
then here is the new prob. Car just straight up runs like absolute ---- like its sitting there missing like crazy or running on only 2 cylinders or something. Thats what it sounds like! Anyways!! My engine was pretty beat so i swapped it out for another perfect running one a friend had! I used everything from my old intake manifold, injectors, wirring harness sensors etc... Come to start it up and its doing the exact same thing it did before with the old engine!!!!!!! What the ---- could be causing this!! No check engine lights nothing!! Its got spark in all cylinders, getting fuel, new plugs, changed dizzy,
the only thing i can think of maybe being the problem is something to do with the injectors... maybe dirty?? Could a bad wirring harness be causing it somewhere to run like ---- like this?? Even without check engine lights?? I dont know im lost!!

Ok guys here is the vid of what the ---- is going on!! The first part of the vid is with the same chip that its been running on for 2 years and it sounds like its missing really bad!! The second part is with my other chip i burned for the stock map sensor and it makes a weird popping snapping sound.....
UPDATE!!!!!!!
ok well i got the car to atleast run now! Changed maps, injectors, and resister box.... but as soon as it hits boost it starts missing like crazy and runs like complete ---- but only in boost!! Here is the vid! Listen to how it hesitates in the vid... Dont mind the compressor surge my bov isnt hooked up lol!!

Re: Weird missing problem!!
check if your purge solinoid and iat sensor wires aint messed up i have a obd2 civic converted to obd1 via a harness and i had the purge solinoid and iat wires sweitched around and the obd2 didtn throw a code but it ran fine but when i put the obd1 ecu in it ran likc ----! and poped my iat sensor i guess it was trying to purge the iat risistor lol anyway just chech your sensor wires bye a good wire diagram not by location but by exact wire color so they match like the map and tps have same plugs but diffrent color just check it out wiht a good wire diagram check all the colors and use a volt meter too lik so you can see the vcc1 wich is the 5 v supplay to map and vcc2 to tps just check that stuff out and double check i dout its the injctors cuz thats wat i thout.. and it wasnt also make sure to tak out you iat probe you have a obd1 car so its in the back of the intake manifold and see if the tip melted if it did teres your problem youll have to replace it cuz it will bbe telling the ecu your intake air teim is like 280 degrees f and it will yank fuel and your motor will run like ----!
good luck

Re: Weird missing problem!!
alright wasnt the intake air temp sensor.! But what i noticed is it does it from the second i start it up cold and it doesnt change as it gets warmer other then get worse. So since thats open loop and its doing it. Doesnt that mean it doesnt run off the any of the sensors until it gets hot? Sooo im guessing its probbaly not any of the sensors. Since it does it while hot?

---- i dont know wat too say im too sleepy sorry so if its running oil loop and stays running open loop thne its the CHT the two wire sensor under the dizzy the cylinder head temp sensor ( the one that the ecu reads)
the other small 1 wire is for your temp guage on you dash!
later nigs
