i have a 87 tii and it take forever to start. it just starts at 500 rpm and then dies. when it warms up it idles at 700-800 rpm but 30 sec later drops down to 500. what can this be? i checked the tps, uninstalled the intercooler and just checked all the wiring and what not. any advice would be great. thanks

 

start checking the fuel system. could be fuel filter if you haven't changed it recently

 

i've been having a similar problem it sounds like the car isn't getting enough gas and the engine shakes real hard and sounds like a lawnmower i give it some gas for about 5 secs and it warms up what could thos problem be? i haven't changed my fuel filter

 

i changed my fuel filter already... what can it be.

 

- idle adjustment
- TPS adjustment
- BAC working?
- vac leaks

 

the car also backfires a whole lot. i tried to adjust the idle, tps,no vac leaks..... can it be the coils?

 

i know it seems basic, but you checked the spark plugs and wires?

 

yeah they're all brand new... just changed them 2 months ago. but i did check the connection and everything is good.

 

timing, idle screw not adjust properly, also vac leak. Maybe low compression.

 

Does it run fine when it warms up? The first few symptoms sound like your motor is shot.

 

it runs fine once it's warm sometimes... sometimes it just backfire a little

sounds like a vac leak to me

you know the procedure.

 

i'll check it again. thanks guys
