hi, long story short i down shifted into 2nd instead of 4th one day while racing and messed up my car pretty bad...

my speed sensor EXPLODED, yeah litterally....and the car drives like complete crap..

i replaced the speed sensor but it still drives like poo....

symptoms are :

extremely rough idle.. like the engine is rocking hard like if it was a muscle car lol

noticeable noise coming from distributor

EXTREMELY bad performance...feels like im driving a single cam

bad gas mileage

car would just...shut off while driving sometimes...yeah just out of no where i would be driving then all of a sudden it just shuts off, motor, electronics...everything...


i just did some research and think its either the timing belt slipped a few teeth or a bad map sensor..idk...im replacing the timing belt and replacing the auto tensioner with a manual tensioner kit as suggested by so many right now since the car has not had the belt replaced for a long time anyway...but is there anything else that could cause these weird things to be happening to my lude?

How did you go into 2nd instead of 4th? lol

And i might be wrong but couldnt you have messed up your cams while all this happened? That could be why your idling so bad.

"How did you go into 2nd instead of 4th? lol" -
while turning a hard left while shifting, some people tend to pull toward them from the force of the car while shifting causing a down shift into 2nd from 3rd instead of going straight down to 4th...whatever everyone in the world of manual has done it, including stalling a car... anyway...

yeah about the cams...I HOPE NOT...im getting my manual tensioner kit delivered tomarrow and im going to put it in along with a new timing belt....hopefully i do it right and it fixes my problem

Oh i thought you meant like from 5th to 2nd.

well good luck with it and that it fixes everything.

check your spark timing on number1 cyl.

is it possible that you skipped a tooth on your timing belt and your cams arent quite in sync with everything else?

lude203

yeah thats what i'm thinking because i read online that if your timing is off it causes :
shaking steering wheel (which i have), distributor noise, poor performance, bad gas mileage, rough idle, etc. which are all my symptoms....at first i thought i bent valves or something so i was in the process of taking off the head of the motor when i realized that the timing could be the problem and that i should switch to a manual tensioner anyway....

BUT

i have never done a timing belt before.....i get the concept and read the manual over and over and watched videos online of how to do it but does anyone have any tips for me?? i really don't want to mess this up seeing as how h22's are interference motors!

You probably bent some valves.
How would a speed sensor explode? Hmm

Only way to check is compression test/leak down test/tear into it.

Lemme through my 2cents worth in here since i just did a head swap and a timing job.

one, your map senor, the one that connects to your intake manifold shouldnt be bad. if that goes your car just wont start or stay on, and their fairly expensive.

two, when i put mine back together my timing was off but only a tiny bit, it was my distributor that wasn't connected correctly. on the wheel of the two teeth on the distributor is a flat side that has to be lined up with a small line on the distributor, dont forget that. bad explaintion but i can get into detail if you need.

if your belt skipped a few teeth leaving your timing off and the car will still start just starts bad, then chances are you might of damaged the valves. if you did then you need a head swap or you need to rebuild the valves and or valve seats etc. Go to the auto store and buy a feeler gauge. take the valve cover off and find TDC cylinder1 through 4 and see if your valves are off.

three, if your doing a timing job and you think your belt might of skipped teeth on the cams, then when you turn your crank to TDC1 useing the cam arrows it may be off. so take out the spark plugs put a wire cut hanger or a very long thing screw driver into the cylinder, wait for it to reach the top and you have TDC1, its not 100% but its damn close enough. do your timing line up your cam gears. i took off the bolts to the cam shafts and let them loose so that i could mess with the cam shafts, get everything lined up and then bolt it back down.

I'm no expert and i probably worded it horribly but thats what i did and now my lude and its new head swap is running like a champ.
