my 87 n/a had a real hard time starting it relaced alot of stuff and now when i get it started it wont idel at all i tryed searching but just kept getting proxy errors but anyways i still have a hard time starting it and then when i get it started the spark plugs and black when i take them out

 

Start off by doing a compression test.

 

Black plugs are a sign of runing rich. As white87fc said compreshion test. The first thing comes to minde is blown apex seals. Main or side.

 

did a compression test and it was good

 

What were the numbers? Is it smoking? What does the exhoust smell like? Does the coolant smell like fule? Is your OMP rod stuck up?

 

Maybe the car is running so rich that it floods the engine on the start up. what kind of stuff have you replace? Have you replace the vacuum that goes from the boost sensor to the intake manifold?

 

Yea the injectors may be just shot wide open. Unushual. He does not have a boost sensor it is a N/A therefor it is a presur sensor MAP and will not caus this.

 

OMP rod?? and i replaced fuel pump fuel pump relay leading ignitor and coil and injectors and fuel pressure regulator and it smokes a little but just smells like normal exhaust the compression was at about 90 for both

 

TPS maybe?

 

It is more or less a long shot but if the rod is stuck up or open it will cause more oil then needed to be injected into motor and smoke a lil. It is the rod connected to the TB facing the pullys. It goes down to the OMP it should swival up and down as throttle is applied.

Other then this I dunno it would prolly be over my knowledge. :-(

 

there was a rod that was connected to i guess what was the OMP the rod moves the the thing its hooked up to was stuck up and would not go down

 

View the attachment for help. The rod should swival freely up and down with throttle. If it does not you need to find out why.

 

the rod does move freely the the thing is stuck like wide open

 

Well fix it lol

 

lol how do you fix that or do you know if its easy to replace cuz i have a spare car

 

I dunno why its stuck without looking. It is just on a spring. I mean look over it asses it and see what you cant come up with. As well there held together by the bolt on the end. You could disasemble that half and inspect it. If you want and have a spare Zenki as you say you can swap the TB from it over. But I would rather just fix it.

 

okay cool thank you very much for your help

 

dude...
i doubt it is your omp
its hard to start maybe because it was flooded...

how does the car run now?

 

i replaced it because the spring was extremely rusted but it didn't help any the car is still really hard to start and still does not idel at all

 

Yea the MOP when stuck can just caus a lil smoke when runing. It was just something that needed fixing. I am not to sure what your prob is. Bad compreshion is all I can come up with right now. Sorry.

 

compression is good could it be hte CAS causing this?
