Yes. i have a 91 civic when im going down the road it sounds like a chain is binding up. so im woundering if there is chain that links the transmission to the engine.

 

Nope. That doesn't sound good whatever it is...

 

I love these descriptions of the sounds that people's cars make. How are we supposed to even begin to guess what it is? There is no chain anywhere on a Civic. The most common metallic sort of sound is the exhaust heat shield rattling. This will be heard from underneath the car near the center.

 

no its the chains on his tires guys theyre binding up on the truck pushing his civic

 

you only here it when im in the gas. really bad if its bogged down. and ECU is putting out code 16. it is a 5-speed.

 

there is no code 16 for obd0 recount your blinks.


Note: OBD0 is for ECUs in the years 1988 - 1991.

If codes other than those listed above are indicated, count the number of blinks again. If the indicator is in fact blinking unusual codes, subsitute a known-good ECU and recheck. If the indication goes away, replace the original ECU. The Check Engine warning light and ECU LED may come on, indicating a system problem, when, in fact, there is a poor or intermittent electrical connection. First, check the electrical connections, clean or repair connections if necessary. If the Check Engine warning light is on and LED stays on, replace the ECU.

 

it blinks 16 times. the paper i have says its fuel injector.

 

on obd1 and obd2 systems yes code 16 is fuel injector.
yours is obd0
do you have dual point?

How do i figure that out.

 

The dual point system has 2 fuel injectors on the throttle body. Atop the throttle body is a black air box that says "dual point." The MPFI system (better) has 4 injectors in the manifold near the head, one for each cylinder. I think in 1988-91 models only the Si had MPFI.
