the fan relay sensor is out of it.
take his cigarettes off him

pontiac first started out in 1926
Your 1987 Astro might go full throttle when the engine is started because the throttle is sticking. This could also be a problem with the starter or the ignition hanging during the start.
stuck throttle butterfly plate
Pontiac made the GTO. And no it was not started in 1968 as stated above lol.
Pontiac started it's business in the early 1900's and have come out with multiple models of several different cars. Some of these early models include the Pontiac Fiero, and the Pontiac Grand Am. The Pontiac Tempest, and the Pontiac GTO are also good examples.
Pontiac made the Firebird car. Pontiac started making the Firebird in 1967, and the latest model was produced in 2002.
Clean the throttle position sensor and throttle plate, then use electrical contact cleaner to clean the air flow sensor at the air filter.

Throttle plate stuck Control cable bound? Throttle body assembly?
Why change the engine ? A head gasket replacement with a head skim should cure this problem & would be a lot cheaper than a engine change best wishes
GM started building the Pontiac Bonneville in the 1950s. It was the company's first top-line model, and served as a luxurious and high performance vehicle.

The best place to start gaining information on starting a dealership would be either on the Pontiac website or at a Pontiac dealership. Feel free to ask those who have already done what you are trying to do for advice. Speak to the current owner and find out how they started out and what tips they have for you.
Could be the throttle position sensor
Check a fuse
If it runs with the choke on, and then- just won't with the choke off,, gas flow is restricted..
The LJ designation was a "limited" or "luxury" tag never officially defined by Pontiac. The model was a differentiator from the SJ model. Pontiac started using the J and SJ option identifiers in 1969. These names were borrowed from historical Duesenburg models of the 30's.
First take out the blower motor on the passenger side. Just the motor not the whole assembly. There is a bracket on the end of the started and take that off too. Disconnect wire from starter and take off the 2 bolts holding the starter. Also disconnect transmission gear selector cable by the starter. All this is a tight squeeze but it can be done. Or go to Autozone.com and they have a diagram that helps too.
Most likely it's a vacuum leak.
There are a few things that could cause an 87 Chevy Astro to idle high when it is started and warmed up. It could be a bad fuse, a leak in the vacuum, or an issue with the throttle.
Could be a Throttle Position Sensor.
