Did you receive those weather seals? How'd they look?


I have an 87 turbo. Some years ago, it had an issue where startups took too many cranks and the cold idle was low and often stumbled enough to stall.



After a test using a voltmeter, it was apparent that the cold start injector thermo time switch (left side threaded sensor under intake) was out of spec.



I bought a Beck Arnley unit from RockAuto which luckily turned out to be a repackaged OEM part. The truck starts up instantly and idles up great.


Perhaps a quick check on that sensor could net some answers.


The poof of smoke on startup is characteristic of failed valve stem seals. Is it blue smoke?
