GMC C1500 ENGINE PROBLEM

1987 GMC C1500 • 100,000 miles

Could the timing cause 87 gmc serria 350 fuel injected motor cause hard starts and idle surge on start up but once it warms up it smooths out if not any other ideas done replaced tps and temp sensors and vacum lines any ideas on what else it could be would be great
