Bad Engine?

I took my 87 t2 out for a drive the other day and when I really got on the gas it hesitated and jerked. Help!

Wow, can you like give us more details???

What have you done to the car lately?
What kind of gas are you running?
What kind of mods are on the car?
How fast were you going?
What RPM's was this?
How much gas was in the car - gas gauge?

I was probably doing 35 in second and the rpms started around 2k and when I got on it it would jump from 2k to 4k very quikly and it kept going back and forth. I just bought the car so I dont know much more about it. There was a half a tank of gas. The car has been street ported, K&n air filter, RB turbo back exhaust.

Is the stock computer's still installed and connected, is there a 2nd piggyback fuel computer to compliment your stock computer, or is there just one aftermarket computer (ie Haltch)?

If you're getting hesistation it could be anything from a clogged fuel filter (or gasktank fuel strainer), leaky intake manifold, vacuum leak, dirty fuel injectors, oversized aftermarket fuel injectors being run with the stock computer, etc...

If the engine's been streetported, chances are there are more aftermarket modifications that will require some checking & tuning on your part.

Search for "TPS adjustment" and that should help you out.
