2002 Rough start

Im really new to the whole import/newer car scene. Im used to working on older cars with basic computers and distributors...so this problem is out of my reach.

So I had a clogged cat and the car wouldnt rev above 2500rpms. Gutted the cat (temp fix) and after that the gas mileage dropped massively. So I thought that it might be fouled plugs...changed them and thats where everything went to hell...

When you try to start the car sometimes it wont turn over. It tries but wont catch. Although when it actually does catch it runs perfectly...the gas mileage improved a good bit to. So the only problem I have is the engine starting.

Any help would be great.

How many miles on the 2002? If you start it and turn it off and then restart it without incident, you may need to change your fuel pump. I have a similar problem which is from a cold start it takes a while to crank, but once I restart it she comes immediately to life.

You may also want to check your crankshaft position sensor. There was a recall on that on the 2002. I don't know what to say to you about the gas mileage.

There are about 108,000 miles on the car. It just weird that I started having this problem only after I changed the plugs. It wasn't a problem at all before the new plugs.

We can always blame the MAF, seems like the only time our cars truly run bad is when the MAF goes. As KeVQ said, the starting issue may be the crank sensor. The crank sensors they used to use is some cheap plastic crap that would develop cracks in the plastic, causing the sensor to fail. The revised sensor is now metal, and you may want to change the cam position sensor as well since they are cheap and they are the same sensors.
