my 81 capri keeps shutting off at idle in drive this started today before it was fine the only changes i made recently was to install a autometer tach i attached the wire to my neg msd blaster coil post and hence then the autometer tach works but bounces irratically from time to time which i found strange ,anyhow today she was fine then started shuttin off at idle in drive can it be my msd blaster coil goin bad? the new tachs connected to it and has symptoms described above but the factory tach works fine can this be it any sugestions appreciated i wouldnt know if my coil would make it shut down at idle in drive ,in park she st5ays running help guys.

disconnected the tach and see if it still shuts off might be the tack

[85bubblebackboy]

how would the tach be causing that isnt that an instrument of measurement i know my factory tach is not hooked up to the coil if so i havent noticed it the symptoms seem to make me lean towards the coil being the problem im boggled this never happened before.

If the tach is bad or the tach wire is shorted out somewhere it can ground out the ignition. Been there done that LOL!

[83rsturbo]

well you said it only started to die since you connected the tach has to be a short there some where

[85bubblebackboy]

[my83horse]

Process of elimination. Hook everything up the way it was to begin with and try it. If it is fine start replacing with your new stuff until the car dies at idle and then you will find your problem.

[85bubblebackboy]

yeah i put it back to the way it was and the problem continues i think its a ground problem or a bad coil.

[83rsturbo]

could be the starter switch

[85bubblebackboy]

well shes fine in park , in drive or reverse she shuts off what can this be?

[eeprete]

does it happen in neutral? neutral safety switch perhaps?

[donutbandit]

How in the world could a starter switch or a neutral safety switch cause a car to shut off once it's been started? C'mon guys, think.

It has to be something that was done while installing the new tach. Some wiring was disturbed and some fault was discovered. Bad ground or something.

[85bubblebackboy]

yeah thats what im thinking i just cant find anything still looking len its driving me crazy i miss driving her guess its mechanic time....

[83rsturbo]

well the ignition switches are noted to do this in the foxes. nine is acting up have to change it. The car stalled just pulling away from a stop sign

[rcoupe93]

maybe you knocked a vacuum hose running the wires causing a leak and then when car is put under load in gear it shuts off.

[85bubblebackboy]
