Ok my motor for some reason when you first crank it up it runs great then when it warms up it starts missing and sputtering and sometimes will die. Let it cool back off crank it up runs great again. It has had a recent tune up. I replaced the pcv valve. I dont know if it has anything to do with it but I know it has a bad air intake leak. Its a stock 1.3L motor. 87 Model if anybody knows anything please let me know.

Thanks alot,
Corey

I had an two 88 models and an 86 and i had to do away with the stock carb to make mine run right. I used a early 70's model holly one barrel with an adapter plate to make it run. when i had the stock carbs on the 88's they run fine when i got them then sat up for a while and started the flooding and stalling at idle.!

check your carb. most folks run a manual choke

im thinking its vacuum related or maybe the EGR valve or the HIC

It could be that when it warms up, the thermal vacuum switch opens a vacuum circuit that has a bad leak.
