I rebuilt my engine a few months back, and it now doesn't idle quite right. There is vibration, and the RPM needle fluctuates just a bit. It didn't do this before, and I also saw a slight drop in MPG since. Other than idle the car drives fine. Even kicking on the AC compressor fixes the...

I posted this in the Mazdaspeed forum already but there doesn't seem to be much activity there. I rebuilt my engine recently and now have a whining noise coming from the belts that I can't figure out. I've already done a lot of troubleshooting and it has stumped me for about a month now...

I just got my car running again after a rebuild. It runs great, just like it used to, except for a strange whining noise near the left side of the engine (belts area). I can hear it over the engine noise when driving, and it becomes more high pitched at higher RPMs. I took each accessory belt...

I took my car in for an alignment and found the front-left tire was outside the adjustment range. I recently replaced all struts, strut mounts, and front control arms, and I'm wondering if I installed something incorrectly. On my rx7, the front strut mounts need to be installed facing a...

I've got a bent rim and am having trouble finding a replacement. I don't need a brand new, perfect wheel but I don't want one that's trashed either. It doesn't have to have the center cap. Thanks

My car has misfired one too many times due to bad coil packs or plugs over the years and the cat is clogged up, causing back-pressure. I don't know much about cats and have a couple questions. 1. Does the MSP have the same cats as a standard protege? Do the cats on rockauto look like they're...

My car was driving fine this morning until I stopped after about 5 minutes and idled when it suddenly started misfiring heavily. The car barely stayed running. I pulled a p0300 random misfire code, and swapped in an older, used set of plugs and it ran fine again. I'm going to get a brand new...

NOTE: PM me for a link to more pictures. I didn't want to retake all my pictures with the forum sign. 2003 Spicy Orange Mazda Mazdaspeed Protege for sale. 136k miles. I purchased this as a non-running car one year ago and have replaced a large number of parts including the engine to make it a...

I have been in the long process of getting an MSP running, and after an engine swap, new head, new rod bearings, and a whole lot else I have it running again. It runs and drives OK but the idle is a little low, and my vacuum at idle is only 15psi. All the vacuum hoses seem to be connected and...

I'm at 146k miles on my original struts and springs, so it's time to replace them. I really like the factory setup and ride height so I'd like to stick with Tokico blues and the racing beat springs if I can. What are my options for purchasing these? I have heard the rear struts are a different...

I took my exhaust manifold off and had it welded because it had cracked, but I realized it is not flat anymore. It's not even close. You can lay a straight edge across it and see a big gap on one end. I have stripped out two of the bolt holes going into the head now and I think this might be...

I discovered today that my turbo is loosing oil which is forming a puddle in the air intake side. I'm looking for feedback on my replacement options without spending over $1000 if possible. I also want to buy something that will last another 10 years, so a new or lightly used turbo is what I'm...

I am struggling to get this car started after swapping engines. This is the first time I have ever swapped an engine, so I am not sure how to troubleshoot the problem and I could have overlooked something simple. Background: A few months back I bought an MSP with a blown engine. I swapped in a...

I recently bought an MSP with a supposedly blown engine so I could learn to do an engine swap. I know a good deal about these cars but I am not a mechanic and I am pushing the boundaries of my knowledge with this. I took the old engine out which recently had a new head put on, but supposedly 100...

This is probably a dumb question for many of you with experience, but I have never opened up a transmission before. Long story short, I recently bought an MSP with a blown engine and am replacing the block. The seller told me the transmission had been replaced a year or so ago, and didn't know...

I just drove 800+ miles yesterday and this morning my oil pressure light came on. Looks like I am down at least a quart of oil, maybe 2. I have had problems losing oil for nearly two years, but I just did a bunch of maintenance that I thought would fix the problem. I was losing oil in this same...

I am getting ready to change the valve seals on my MSP but cannot figure out which valve spring compressor will work. I found other threads here with links to pictures and websites but they do not work anymore. Can someone point me in the right direction?

Hey guys, I recently started hearing a popping noise from my suspension when I turn sharply or go over larger bumps (even slowly - like a speed bump). It sounds like it's coming from the front end but I can't be sure. It doesn't happen every time, but it's a very noticeable noise when it does...

Last week on a trip I noticed s vibrating feeling and thumping noise coming from my front end. I drove a few hundred more miles home, jacked it up, and grabbed the top and bottom of my passenger tire and pushed it in and out. It had a significant amount of play (inches of movement). I bought a...

Two weeks ago my car (137,000 miles) very suddenly started to run rough and then the third cylinder started misfiring consistently, making the car barely drivable. I tried swapping coil packs, plugs, and wires but nothing changed. I then tried to swap the third and fourth fuel injectors to see...
