FlyTSI Posted February 9, 2009 Report Share Posted February 9, 2009 My 87 has been running bad whenever the boost gauge hits 0 or higher. I check the vacuum advance and it test ok. Just for kicks today I unhooked the vac line going to the advance and the car runs a lot better. It was stumbling and almost like it was running out of gas before. Any ideas on where to start looking. It has a 1g mas on it if that means anything. Thanks in advance. Kenny Link to comment Share on other sites More sharing options...
Fanta Posted February 9, 2009 Report Share Posted February 9, 2009 check to make sure all your IC hoses are tight and not cracked/loose also when it stumbles, see if your exhaust looks rich Link to comment Share on other sites More sharing options...
jclose Posted February 10, 2009 Report Share Posted February 10, 2009 Check the vac lines, and anything that has air running through it. You can use a piece of 3/8" fuel line to listen for leaks with the engine running. I've had a problem like this, and it seemed to be related to that. Like Fanta said check ic piping too. Maybe the intercooler as well. Link to comment Share on other sites More sharing options...
TopDawg_43 Posted February 10, 2009 Report Share Posted February 10, 2009 Are you sure you got a turbo 1G MAS and not a NA? Sounds like the ECU does not know how to give more fuel to comp for the boost. Link to comment Share on other sites More sharing options...
