i have a 95 ls with a jdm b20 and after the motor swap everything went great
but its no that great anymore.. every once in a while when i start the car the tach jumps like crazy my shift light flashes and everyting but the idle is smooth...when i rev it up it misses when i drive it it misses realy bad like the whole car will cut out then come back on ...but it only cuts out when i give it gas if im just cruisin the tach will still jump like crazy but the car dosnt cut out....

i thought it was my ignition modual so i put 1 of my 3 spare distributors on and no luck.i thought maybee the groung wire from the valve cover to the body(didnt have one on)so i put one on still no luck....ALSO NO CHECK ENGINE LIGHT

is it possible its the ecu IT ONLY HAPPENS ABOUT EVERY OTHER DAY OR SO


PLEASE HELP ME

 

Hmmmmmmm. thinking

 

hey now its getting worse sometimes it is hard to start sometimes it wont start sometimes it will run like a champ also it backfired and and made a loud whining noise (kinda like turning the key while the car is running) after it did that it runs smooth but now idles @1500 now im starting to think timing belt may have skipped a tooth ( but i cant tell or not) also my speedometer was going crazy


oh one more thing to add to my delima is that it will just shutoff while driving


my nerves are shot and im really starting to get pissed i think i might take it to the dealer

 

OK, if you have a multi meter use your MC Dwell function and check erratic readings on the test tach lead located on your driverside harness. It's the one that has a rubber plastic cover over it. If the reading are erratic(not stable) chances are the ignition coil if failing. If the igniter(module) had an erratic signal your car wouldn't run. Good luck!!

 

I'm banking that your coil is toasted.

 

Sounds like something is short circuited...some where, not sure sorry

 

i found it it was a loose ground wire by the thernostat duh

i feel like a dumbass
