I started it up and it ran a little rough at first, but then cleared up was running great.
I put in a small bottle of fuel injector cleaner, and filled the tank everything ran fine.
Once I got back home, I sprayed degreaser on the motor and rinsed everything off.
I started it up again and, drove out of my neighborhood it was running rough and then died, NO POWER the engine was still running but the car will barely move when I put my foot on the gas.
Could I have shorted out the coils when I washed the engine, i have pressure washed this motor many times before and had no problems.
Help......
Well, this is a Mazda MPV forum. But, sounds like the coils to me. Over time coils may develop cracks from engine heat, the last power washing did em in.
DO NOT BUY AN MPV van - it will cost you a lot in repairs & Mazda doesn't care!
Thanks :confuse:
I had a few replies back - Transmission, PCV pipe leaking, Ignition coils anf fuel pump/filter.
I have eliminated the transmission and I am still unsure about the PCV pipe and Coils. I have been putting in a bottle of fuel treatment stuff in the tank everytime I fill up and it seems to make it go away sometimes for short whiles or longer. So i am leaning more towards the fuel pump/filter/incectors.
Is there away to test these 3 things or how do I go away bout cleaning them? :sick:
All started with running a little rough when first started. Auxiliary fan wouldn't shut off. No big deal. Replaced problematic valves, thermostat control, coils, wires, plugs. Same problem shortly thereafter. Took to dealer, told blown head gasket. Had this done for $3k. Got vehicle back and heater still didn't work. Started to run rough less than 24 hours after. Dealer is now telling me it is a cracked head gasket. There is a problem with the design of these engines. Good luck to all, my suggestion would be to get rid of any MPV. There is a real good reason why Mazda discontinued the vehicle. Mine is a 2005 with 70k. When we bought it, there was less than 30k on it. Over the last 6 years, we've only driven the damn thing 5-6k/year. Does that say enough? Had something wrong with it the whole time.
I have 195,000 miles on my 2005 MPV and have been very happy with it, but these ignition coil problems are getting bad! The first ignition coil was replaced in January 2013. The second ignition coil was replaced in October 2013 -- along with the EGR valve. Today, my mechanic told me that a third ignition coil is now bad. Maybe I'm being foolish, but I'm going to have this one and the last three replaced as a preventative measure.
