Throttle Response and bad fuel filter = not good?
I have had my car for about 4000 miles now. When I am curising at lets say 50, the rpm will go from 1500, drop to about 1000 for maybe 6 secs, and than shoot back up to 2000, its not as long if i give it any gas. It seems to be bogging really bad. I do not know if the fuel filter is bad or not, but the last guy who had the car definetly looked liked a cocaine dealer, so maintenace wise i dont think the fuel filter nor transmission fluid has ever been placed. So its my throttle response and bogging a proble because of the fuel filter or is it something else?

Change the fuel filter anyway but it is not your problem.

When you buy a used car, maintenence is always a question. Unless you know for a fact that the maintenence has been done, you must assume it has not been done. That means that you have to do it. You should replace all fluids:
coolant oil rear end tranny You should inspect and replace if necessary: belts hoses spark plugs air filter Replace the fuel filter. |
As soon as I got my car, I parked it. I put it in the garage on jackstands. It sat there for over a month while I did the following:
Fuel Filter Silicon hose job Mazda fuel line recall kit Fuel pulsation damper Fuel injector overhaul Check valve testing/replacement Solenoid testing/replacement Rewrapping of the main engine harness Fuel pressure gauge installation Fuel pressure regulator testing Spark plugs Spark plug wires New oil + filter New coolant New transmission oil New differential oil New airbox filter/airbox mod New oxygen sensor Installation of an aluminum AST (air separator tank) Brake booster line/check valve It was a lot of work, but my car has been good to me since then. Most (if not all) of the above should be mandatory work on a used car with an unknown maintenance history. (IMO) Sonny |
