I have a 1993 SE Auto. I have CAI,UDP,Y-pipe,B-pipe and strait pipe. My timing is around 20 or so. My car bogs down hella. I mean lot. Like my 60' times at the track are like 2.7-2.8 range. Its horrible. I need help, Ive read up a lot on things like this and done things. Ive changed the Knock Sensor, 02 sensor and coils. It still bogs down a until about 3-3.5k. I need any help on what you think it might be. Or any help on what else i need to check. thank you. I just really want it to go away so my car can get a good launch. The low end deffinetely used to be way better so i am lost as to why it went to SH**. thanks

 

Change or clean your injectors? Spark plug wires? Plugs? Distributor Cap? Distributor Rotor? Distributor? Fuel Pump? Fuel Filter? EGR Valve?

Too many things could be wrong....thats what sucks.

 

get a 3500 converter so then you will start off in your power range. No I am just kidding that is too much converter for everyday driving.

is the car running perfectly but just lacks power down low? Or is it missing or smell like raw fuel coming out the exhaust?

Have you checked the VTCs to see if they are working properly?

Do you have heavy 17" or 18" wheels? That will hurt more than you know.

 

Do the VTC's affect low end?? Well if they do ill deff check them out. sometimes i smell gas when i drive but only really on start ups and the first few minutes. thats is the next thing i was gunna check is my injectors. but my MPG is still good. so im confused.

 

well its just low end. but once it gets above 3k its pulls real hard. i do have 17's but i had my stock 15's on at the track which is what i had on for those 60' times

 

I heard somewhere that it could be the timing chain and or sprockets. My friends dad who is a mechanic told me to change my timing chain at about 160k. im at 157 right now. do you think that could have something to do with it???
