Rough starts and occasionally "stops"
5

Asked by GuruXZ5X3 Oct 03, 2018 at 11:31 AM about the 1987 Volkswagen Jetta GLI FWD

Question type: Maintenance & Repair

Hi...
My son recently inherited a 1987 Jetta GLI from his grandmother. 71k
original miles... It was running/idling very rough and not a lot of power... I did
new cap/rotor and plugs and wires. Runs and idles much smoother now.  
Problem is that it still is a rough start. It takes a bit of cranking till it turns
over. Once it does, idles smooth.  He also claims that it occasionally stops
(usually at a a red light). Not stalling with a shudder... Stops like someone
turned the key off.   I know this model has reported fuel pump issues.
Based on this description, can anyone suggest a logical place to start?
Thanks, in advance.

Thanks for reaching out Ed92626... there is a perforation in the tailpipe just before the muffler.... I put a patch on it till I can get to it, but it's still leaky. That's the polar opposite of a blockage, but could that be contributing? Also, for total transparency.... I changed the wires/plugs/cap and rotor, and coil wire, but not the coil. If you're thinking ignition issue, that might be an easier 1st step.... Your thoughts?
