i have an obd 1 b16 motor with an obd 0 distrubutor in a 91 hatch the car runs perfect ... most of the time. when driving around town the car runs and revs perfectly but when i get on the interstate (speed doesn't matter) for about 15 minutes straight the car starts to sputter and break up , so i put it in neutral and coast for a while and then i can drive again. I have replaced everything that has to do with spark and cleaned my injectors and put in a new fuel filter but i still have the problem any ideas would be greatly appreciated!

 

do you have both O2 sensors hooked up correctly? Also have you checked your timing?

 

well i have only one o2 hooked up because of the diff. in the exh. manifold my timing is a little bit advanced on the distributor but my mechanic told me that would not cause my problems. any ideas????

 

well you definetly need to have both O2 sensors hooked up correctly!!! that caused a lot of problems on my car.

 

Guarenteed. You need to have both of the O2's hooked up CORRECTLY!

Don't beleive any of the garbage that you can run just 1 O2 on your car.

You need both O2's hooked up correctly! I had the exact same problem you had and it drove me nuts. I bet if when it starts to stumble over itself on the freeway , if you pulled off the road, turned the car off for a few minutes, then started to drive again it would go away. Then a few minutes later it would do it again.

You have to fit your O2 issue.

 

that is exactly whats going on!!! i have replaced all kinds of stuff b/c my mechanic swore that is what was wrong but nothing ever worked. now the only problem i have is that i just moved to orlando and i have no clue where to find an ok shop to work on my car. Do you know of any shops in the orlando area?
