          First gear in a e21 m10 is SO low that a lawnmower engine would make that gear feel good. I assume you have done cap/rotor/plugs/filters?

            i did the filter but not the plugs and such , do you think its the reason tho??? because it pullls ok in first?? i just need to fix the rust and drive the car .

            here is an example: went for a little test drive today . The car idles like crap . and then it will just idle high for a bit and then it will go back to Normal?? the engine is dirty as hell though , do you think with a little clean up things will be better?

            thanks for the help , i really appreciate it .

              Check all the vacuum lines yet?

              Clean the ICV?

              Clean the injectors and replace o-rings?

              Check and/or replace the spark plugs, ignition wires , coil, distributor/rotor?

                Oh yea, those O-rings dry up like little turds. Do a tune up - and get something to clean the valves. Always run chevron gas in a CIS m10 - helps alot.

                Like I said, first gear is a joke in e21m10's.

                  you said.. i did the filter, can you clarify that? fuel filter or air filter? Both should be replaced.

                          We are aware of that but what about developments with the rust bucket?
