hi,

im a newbie so please excuse the beginner's questions.

I have a 1975 1.8L L-jet. Currently the car will start, but not idle at all. I checked all the vaccuum lines in back and cant find anything wrong with them. The car reads as having between and quater and half of a tank of guess, which i put in.

I just replaced the battery and i can hear the feul pump humming when I turn the car on.

I am baffeled as to what the heck is going on, any help would be appreciated.

Thanks.

Welcome I dont know a damn thing about the 1.8 injection, but I'm betting someone on here does (I lied.. I have a clue but I dont know enough to help out unless the car is in front of me)

CHT? Vaccuum leak? TPS?

i'm just guessing here ...
Andy

Yep. one vacuum line off and they die pretty easy.



B

any advice on a good way to check for vaccuum leaks because I think ive dont a good job, but have found none.

thanks again

i'd say spray some carb cleaner on the hoses and TB and filler cap, but if the car isn't ideling, that's not going to be easy

does it run if you hold the throttle open by hand?
Andy

Very important that the oil cap be 100% sealed. If you just added oil and it didnt run after that.....

I had the same set-up years ago 75 1.8 l-jet. Didn't like it.
Always had problems. Went through everything. Ran good, sometimes. Wouldn't pass smog. Sold it.

Anyway, check the position of the flapper in the air flow meter ( potentiometer? name? ). If it stays shut while cranking it will start on cold start injector only and then die.

Make sure that flapper is able to move freely. There is a plastic lid on top of the AFM that lets you fake the brain out if you open it up. You may need an assistant to help you.

I have a spare one here, if you want to try it. Brain, too.

spare assistant and brain? do i understand you correctly?

Sort of.

I have a spare AFM ( air flow meter ) and brain ( 1.8 l-jet specific computer controller ).

I'm offering to loan them to you.

Not my assistant and my brain, as I am currently using them both.
