man my car is driving me nuts !
have any of you had a problem like this........
car idles and run great all over town, yet when i get into some boosting, say like 7-10 psi i start gettin this pinging, sound
does not sound to be mechanical sort of pinging
more of less fuel/ air or injector timing off.
something along that line
heres a lil of thing i have checked and tried in my attempt to fix this
*i have a new walbro and a working regulator, the boost line to the regulator is good as well.
i got a guage on the windshield and the Fp rises with boost.
*i got the delco 43ts plugs at .035 all clean and new, new kirban wires for the 85's and a new alternator,
*ground straps on the coil / module
*fuel injetors are the #36 installed last winter
* have new seals on a Limit turbo
* new o2 sensor
*run 94 octane with 3 gallons of 110 turbo blue
*blocked egr valve off
*tried various mafs
* have proper iac and tps setting
*car does not smoke and has new headgaskets.
*new valve springs
i have the 87 caspers module when i switched to 87 ecm last summer, i have a casper coil pack coming this weekend.
i am gunna go unplugging the cam sensor after work and go for a ride. other then that im stumped
i mean, the scanmaster shows no error at all and im not running overly rich
about #38line off on a jay carter 93 chip, i think its 17 degrees of timing. i aslo tried a thrasher 92
the car is not bogging down or losing power at all, it wants to keep going, but i wont let it, due to not wanting to cause major damage
i dont think it could be the timing chain, its a 64K car thats never even seen the track
any of you guys have problems like this? i know i read some posts, but they were not 2 helpful
maybe ya guys could throw me a frickin bone here
sorry the post is soo long, but being more in depth, stops having to post 45 times with updates
