i just baught a 2001 volvo c70 and it hesitates when i take off and when i am not accelerating around 2400 rpms, i have changed the fuel filter, air filter, spark plugs, added a bottle of Lucas fuel treatment, also patched a hole in the ecu cooling hose.

Who's to say damage hasn't been done to ECU injectors are run by transistors in ECU could be powder from aluminum housing floating around in there who know what els could be affected.. Any codes?.. could be coil, or bad coil boot.

no codes but there was some oil on two of the plugs that leads me to belive there is a bigger problem... doing a compression check today to check rings and exaust valve....

you sure its oil not just wet.. or possibly oil leaking into plug cavity from leaking valve cover gasket.. wouldn't hurt to do a compression test anyways.

by oil on the plugs just making sure you mean on the tips and your sure its oil not just gas mixed with carbon from the plug.
