Hey i just bought a 89 na w/ about 160k on it..it was my friends and it didnt run soo since im a mechanic i diagnosed it (it hasnt ran in about 4-5 months and be4 he had it send to a gradge to getit fixed it hadent ran it like 2-3 years) soo i found out it was the fuelpump...sooo a new pump, plugs, filter, and 1 plug wire later it ran....kinda..i hadta unflood it 3 times and i had to push the pedal to the floor to get iit started and it woulndt idle untill it warmed up comsiderbly and i was driving it around and all the sudden the check engine light came on and it had reallllly shitty pick up like if i would floor it it would just about bogg down and stall....i havent looked into it real hard yet so im askin you guys.....any sugestions...thanx sry this post was so long

 

o and the auto belts dont work...any suggestions on that...fuse maybe....somewhere

 

for the belts take the car to mazda they will fix them for free.....it just might take them a while.

 

My guess would be the TPS is either fried or way out of adjustment. The TPS (throttle position sensor) went bad in my T2...experienced the same problems...no acceleration, bog, stall, check engine light, etc...



Here is a method of checking codes on the car and cross referencing them to see what might be wrong... http://www.1300cc.com/howto/how2/codes.html



Usually the check engine light coming on will signify a TPS problem or an O2 sensor problem...at least from my experiences. As soon as I put in a new one, the car ran like new ever since



Good luck

 

alright thankx i got the car for 1200 w/ a system its a 98 na 169k and the system is 2 jl w3's,ony 760 amp, pioneer speakers, and pioneer head unit was this a good buy...the car is in good shape almost no rust was this a goos buy??

 

1200 for a running s5 with no rust or body damage is good. Hopefully there's nothing major wrong with the engine. Good luck.

Check the error codes using the link provided. If the check engine light came on, a code is stored in the ECU. It helps to know what that code is when diagnosing the problem.
