91 Accord dx

well i changed the spark plugs,wires,cap,rotor,pvc valve,and oil and filter. Cranked her up and the car was running real rough. Missing,backfiring,and stalling.

Couldnt even put it in drive it would stall and die. I went back checked over my work(wire order). I even put all the old stuff back on.Then there was no spark at all.Car wouldnt start. I checked the coil(it was bad)Soooooo, I changed the coil and the ignitor.

Starts up now but still runs the same way. So far ive checked the timing,looked for wires that may have been unplugged rechecked all connections an the ignitor,rechecked the plug wires. No CEL neither

Im stumpped ,,,,,car ran perfectly fine before. Ive searched and searched and searched....nothing. Really dont know what it could be anymore....Any help would be GREATLY appreciated.Im trying to do this myself before bringing it to the SHOP

 

if it was running fine beofre then it is something you did or did not ..
i would double chk make sure you got the wires in the proper firing order , make sure plugs were gapped properly , you can only put rotors in 1 way so it cannot be 190 off, did you use factory parts??? i cannot believe that coil and ignitor went bad ,,no offense but if car was running ok before i think you wasted a bunch of money when not needed ( coil, ignitor?,,,again chk your work i feel it is something you misinstalled

 

ok. i stuck a paperclip in the blue two pin connector and got codes 5 and 7.

is the map sensor and 7 is the TPS. Im gonaacheck some voltage in the map sensor and go from there .

Is it possible for the MAP sensor to make it run rough like this??????

 

and yes i did test the old coil and ignitor before changing and they were fried..

 

Timing is set correctly? Firing order is fine? Get that TPS replaced.

 

mmm it does not make sense that as you stated car war running perfectly before you did the work on it and after you replace plugs, wires, rotor ,you found a bad ignitor and coil and map sensor i have seen many coils and ignitors go bad but hardly ever at same time and never when working ok and go bad after someone replaced plugs, wires, rotor cap when they were fine before ..i am a bit stumped on why all these components would go bad on you ,,

 

timing is set and firing order is correct .......changed the map sensor still the same..........

Im gonna swap throttle bodies off my junk car and seee what happens

 

yo amigo if it was running good before you replaced parts it is something you did or a component you installed ,,did you use factory parts???

 

make sure you got right parts in for right year car

 

swapped throttle bodies

all good now

 

All that money for a throttle body?? Thats a lotta money gone to waste.

 

didnt waste money on the coil,,,, it was broken...the car didnt even start ...

map sensor and throttle body came of my junk car
