Hey guys,

I own a stock 99 Tibby 2.0 (200000kms) with a recent cold air intake, and fuel filter installed.

Just wondering if you guys have experianced this before;

Upon hard exceleration the car pulls pretty good, but looses a substancial amout of power @ 4700 to 5000 rpm and beyond. I havent replaced the plugs or wires yet, but will this solve the problem or could it be something else?

By the way, I ordered the JDM VISION Motorworks 10.2mm Racing spark plug wires and NGK G Power Platinum Spark Plugs off of ebay. I've heard that they may be too thick. I know, I know, I should of asked or done a search before ordering these but they were 58 bucks CND so who cares, right? :confused:


Thanks in advance. :D

That will help, but our cars will natually loose power after about 5500. I installed a SAFC and i have dyno sheets to prove that they WILL build power straight to redline, the ecu just richens the mixture and retards the timming so much it wont build power.

Thats stupid, its kinda like reverse VTEC then, hahaha. So the only way to get rid of that SAFC, or can you get the ECU flashed?

Did it do this before you replace the filter?

After watching over a dozen Beta engined cars run on the dyno this weekend I can tell you that your engine is behaving perfectly normal. The only Beta that pulled to redline was Wilbur's 1.8l with the SAFC.

AH HA! Told you so!!:p

Yeah, well when it resets (two weeks time) it still pulls hard. When i want to go stupid fast, i just pull the power connector in the fuse box. Wait 35 seconds, plug in, and hold on tight.

I will still probally say if its been over a year its time for plugs and maybe wires.
