Run out of ideas, could use some suggestions. 1990 1.6 down on power, flames out of exhaust when getting off throttle. Checked everything I can think of.,
No fault codes.
New plugs and wires,plugs looked okay maybe a little lean.
New fuel filter and fuel pressure good
Compression around 185 all four
Timing belt marks good, belt two years old
Timing set at 14 BTC
New fuel pump
Injectors serviced by Advanced last winter
Funny thing when checking timing when blipping the throttle mark would go way retarded before advancing
Car ran poorly all summer except for one day at Putnam Park when it ran strong did a 121.98, no afterfire from exhaust, next time out same issues, any ideas would be appreciated.
