well the thing ran fine. then i decided to change the oil and put new plugs in. it started up and ran fine. then started to bog down untill i hit like 3k rpms. and now i've noticed an exhaust leak. but i was wondering if the exhaust leak could cause the bogging after the cars been warmed up. or might it be something else. i took out th shity autolites and replaces them with ngk's and i just dont get it. it runs fine for a while then all of a sudden if i give it more than a little throttle it bogs. and putters untill about 3k. somone give me some insight please.

 

exhaust leak shouldn't cause the bogging, my friend's car has a million exhaust leaks and it keeps up with modded 5.0's =]

did you get the right gapped plugs?

 

did the plugs already come pre gapped

 

i did re gap the plugs. so there right.

 

02 sensor?

 

just sell it to me , I think its something with 02 also. Just cant figure out why it would do it just from a tune up.

 

yea it made no sence to me either. it ran like a beauty untill i changed the plugs and oil. and lastnight it was feeling like it was shking a bit. but i think i know the problem there because i installed the h brace and i need to hit it with a stronger impact

 

I know several people that have had that car and tried to use a high performance plug, and had a good bit of acting up. you should try a different type of plug or did you replace your wires when you changed the plugs, you may have broken one

 

ok i changed fom crappy plugs to ones supposed to go in the car. and i was thinkin i need new wires now too. but im broke. haha anyone wanna donate a set to the make marks car run again fund?

 

i would replace the wires, distributor cap, and rotor . could be the o2 sensor. also could try putting a b16 head on, that worked for me
