420a Timing Issue

[Narish]

My 1995 Eagle Talon ESi's timing seems to be off, its the 420a Engine.

After changing the water pump I had to re-time the car.

For the Cam Gears. I made sure the timiing marks ((the grooves on the side of the cam gears)) both aligned with each other, the cranks arrow was aligned with the arrow mark on the engine. I put the tensioner on, everything seemed smooth.
Both cams still aligned tensioner on, alan wrech out of the tensioner(slid back and forth with ease).

I rotated the crank twice, lining up the crank timing mark each time. Lining the timing mark up the second go around. The cams were still perfectly lined up with one another.

All though I started the car, took a lot to start it, had to give it some gas. The idle is really harsh until you rev it up and hold it at about 3k rpms, then the idle drops down and chops out.
It's never had this problem until I installed the new water pump and had to re-time the car, but I seriously had no idea whats wrong with it now. Everything appeared to be timed. It was all lined up.

Any help would be appreciated
Better question is would the car even start, and idle/drive at all if miss timed? I can start the car its rough pretty much dies out, sometimes the idle go to normal, until put into drive then its horrid(sounds like its miss timed, but I seriously would be at a loss I've done a timing belt 4 billion times with my other 420As everything was lined up 100%) I drove it around a little bit, if I let off the gas the car instantly drops to about 300 400 RPM, or dies, if i keep my foot on the gas its fine. Also when it dies my oil light comes on, checked the oil it has a little over min. Reverse is out on the car i havent gotten around to a new transmission thatll be next after I can get this problem taken care of.

You never want to drive the car if you think you have a timing issue that bad, you could have possibly just bent some valves and cost yourself a head rebuild.

Double check your timing.

*edit*

And yes it can still run when not timed correctly, so if ever in doubt, dont even start the car untill you double, and triple check the timing.

Thank you, I'm going to double check it and make sure, hopefully nothing else was damaged.

I had my exauhst cam off by one tooth. It started and ran amazing. Had tons of power below 3k but was gutless otherwise. It all depends on how you mis aligned.

Yeah every time I tension the belt, the exhaust cam moves a tooth off(the one closes to the fire wall) Any tips on keeping everything on the marks putting the belt on and keeping proper tension?

When I did mine I used a wrench on each cam sprocket to help hold them from moving while putting on the belt. It also helps to have two people when setting the tension.

When yours was running. Did it start fine and run fine for a couple seconds then sound like it was cammed? Mine I used the obx cam gears made my marks off the stock cam gears. Lined them up like I did all my other 420a motors. But when it runs now throwing three codes . Runs fine still just idles a little funny.

I'm not sure about the 420 but the 4g63 has a tool that goes between the gears to hold them in place. It makes it pretty foolproof.

What's the codes? And when you put the belt on purposely put exh cam 1 tooth forward from your on time mark. So that way when it rolls back on you, it will be lined up. Or fined a better way to hold things, zip ties, big black clips, they make a universal can gear holder for dohc.

Yeah I used vice grips. And I made sure it was off A half a tooth on the crank and the marks all lined up perfect when I tightened every thing down I double checked every thing . But obx cam gears dont come with timing marks. I had to lay them on the stock ones and mark them to use them.[DOUBLEPOST=1416229475][/DOUBLEPOST]Its a map sensor , egr, and o2. Have replaced the map sensor and deleted the egr. When it starts up runs fine for about min or two the kind dies down normal then kinda has a little miss to it. Has a little tick for about the time it takes to warm it up and then it goes away.
