Could a timing belt that was just replaced be off when a 1989 Acura Integra does small jerks and the check engine light comes on while on the freeway after replacing it and the water pump?

i had a horrible idle and occasional die and occasional code 43 in my da9 91 integra and when i had the belt put on befor dropping the engine in the place that did it had each cam gear one tooth in the direciton on each fixed and solved alot of problems, check it real good
